USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 1 General description This user manual describes the functionality of the family of ceiling-mounted motion detectors and light level sensors EMDC. The EMDC product family consists of the following members: ◼ EMDCA using 868.300 MHz radio (main market Europe) ◼ EMDCU using 902.875 MHz radio (main market US / Canada) ◼ EMDCJ using 928.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 1.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 1.3 Environmental conditions Maximum Operating Temperature(1) Recommended Operating Temperature(1) Humidity 0 … 60°C / 32 … 140 F (indoor use only) 0 … 30°C / 32 … 85 F (indoor use only) 20% to 85% r.h. (non-condensing) Note 1: PIR detection requires that the moving object to be detected is significantly warmer than its environment.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 2 2.1 Functional description EMDC product overview The energy harvesting ceiling-mounted motion and illumination sensor EMDC from EnOcean provides wireless motion and illumination sensing functionality without batteries. Power is provided by a built-in solar cell harvesting available light from the environment. EMDC transmits sensor data based on the EnOcean radio standard using EnOcean Equipment Profiles (EEP).
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 2.2 Basic functionality EMDC devices contain a passive infrared sensor that detects changes in the received infrared radiation which are characteristic for the movement of persons. In addition, EMDC measures the ambient light level via a dedicated sensor and the temperature using its integrated microcontroller. EMDC integrates a solar cell that generates the required energy for its operation from available ambient light.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 2.4 Internal product interface EMDC contains a holder for a CR2032 battery and a PIR sensitivity selection switch as shown in Figure 3 below. Figure 3 – EMDC internal view The internal product interface is accessible after removing the wall mount plate.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 2.5 Functional modes EMDC supports six types of functional modes: ◼ Standard operation mode ◼ Standby (sleep) mode ◼ Learn mode ◼ Walk test mode ◼ Ambient light test mode ◼ Factory reset mode These modes are described below. 2.5.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 2.5.3 Walk test mode Walk test mode is used to verify the motion detection coverage of the device via visual feedback from the LED which will blink whenever motion is detected. Walk test mode can be selected using the LRN button as described in chapter 4.1 or using the MODE field of the FUNCTIONAL_MODE NFC register as described in chapter 9.5.11.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 2.6 Reporting interval EMDC will always report the initial motion detection after a period without detected motion immediately. The rate of subsequent updates (reporting interval = time between two data telegrams) can be configured by the user based on different conditions. The minimum configurable reporting interval is 3 seconds and the maximum possible transmission interval is 65535 seconds. 2.6.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 2.6.2 Standard reporting interval The standard reporting interval determines the longest interval between two status updates of EMDC, i.e. the minimum update rate. EMDC can be configured to use a lower reporting interval, i.e. a higher update rate, based on occupancy and available light as described below. But under no circumstances will EMDC report with a longer reporting interval, i.e.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 2.6.3 Occupancy-controlled reporting interval If a room is occupied, then it might be desirable to receive status updates more often to determine the current light level. EMDC can therefore be configured to use a lower reporting interval, i.e. a higher update rate, while motion is detected. The default setting of the occupied reporting interval is 60 seconds.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 2.6.4 Illumination-controlled reporting interval If sufficient ambient light is available, then it might be desirable to receive status updates more often.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 3 Sensor functionality EMDC implements the following sensor functions: ◼ Motion detection using the passive infrared sensor (PIR) ◼ Illumination measurement using the light level sensor ◼ Illumination measurement using the solar cell ◼ Energy level of the energy store ◼ Supply voltage of the backup battery (if present) These functions are described in detail in the subsequent chapters. 3.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 3.2 Illumination measurement (light level sensor) EMDC integrates a dedicated illumination sensor used to accurately measure and report the light level directly underneath (e.g. on the desk surface). This sensor has a narrow aperture and a spectral response optimized to mimic the human eye’s perception of ambient light. It reports the light level directly underneath the sensor (spot measurement).
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 3.4 Temperature EMDC uses the temperature monitor within the microcontroller to detect abnormal temperature conditions (very hot, very cold, quick change of temperature). Due to the limited accuracy of the sensor itself and the temperature offset typically resulting from the installation location (ceiling), this temperature reporting is not suitable for high accuracy HVAC control.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 4 User interface The user interface of EMDC consists of the following items: ◼ LRN button and LED ◼ Sensitivity selection switch ◼ Backup battery interface ◼ Device label Please refer to chapter 2.3 and 2.4 to identify the location of these items. They are described in more detail below. 4.1 LRN button and LED Most EMDC device parameters can be configured using the NFC interface as described in chapter 9.5.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 4.2 Factory Reset The EMDC configuration can be reset to the factory default values by means of a factory reset. Factory reset is triggered by pressing and holding the LRN button for more than 8 seconds as described above. 4.3 Backup battery interface The backup batter interface allows supplying EMDC with a CR2032 battery in case the available ambient light is insufficient for energy harvesting operation.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 4.5 Device label Each EDMCx device contains a product label identifying the product revision, the manufacturing date, the frequency and the device radio address. Figure 9 below shows the EMDC device label for the case of EMDCA (868.3 MHz).
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 5 Radio communication EMDC communicates using radio telegrams encoded according to the EnOcean Equipment Profile (EEP) specification and the EnOcean Alliance Signal Telegram specification on a radio link according to the EnOcean Alliance Radio Protocol (ERP). 5.1 Radio frame format EMDCA uses the ERP1 standard (ISO 14543-3-10) while EMDCU and EMDCJ use the ERP2 (ISO 14543-3-11) standard.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 5.2 EnOcean Equipment Profiles (EEP) and SIGNAL telegrams The data section within EnOcean radio telegrams uses one of the EnOcean Equipment Profiles (EEP) or one of the SIGNAL telegram types defined by EnOcean Alliance to encode sensor information. The EEP used is selected by the sender and must be supported by the receiver. 5.2.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 5.2.2 4BS telegram structure 4 Byte Sensor (4BS) telegrams are identified by the RORG field being set to 0xA5 which is followed by four bytes of payload (Bit0 … Bit31). The payload of 4BS telegrams encodes either the sensor status (4BS Data Telegram) during normal operation or identifies EEP and manufacturer of the device during teach-in (4BS Teach-in Telegram).
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 5.2.4 Supported EEP types EMDC supports a wide range of EEP suitable for different use cases. Table 3 below lists the supported EEP.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 5.2.5 Supported SIGNAL types Table 4 below lists the SIGNAL types supported by EMDC together with their reported data. MID 0x06 0x0D 0x10 Content Energy status (remaining energy) Enabled by default Energy delivery of the harvester Disabled by default Backup battery status Disabled by default Data 1 byte integer value (expressing %) Valid values: 0 … 100 1 byte Enumeration Valid values: 0x00 (best) ...
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 6 Security EMDC supports both standard and high security modes as defined by EnOcean Alliance according to the EnOcean security specification: https://www.enocean-alliance.org/sec/. 6.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 6.2.1 Telegram authentication The goal of telegram authentication is to prevent unauthorized senders to transmit apparently valid commands causing the receiver to perform unauthorized actions. Telegram authentication works by creating a message signature (often called Cipher-based Message Authentication Code or CMAC in short) based on the content of the telegram and the secret key.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 6.2.2 Dynamic security key modification One fundamental problem with both content protection and content authorization is that using the same input data (plain text) with the same key always yields the same encrypted data and the same signature. This enables attacks based on monitoring previous system behaviour.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 6.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 6.4 Secure teach-in telegram Teach-in is the process by which EMDC communicates to a remote device all parameters required to establish secure communication using a radio telegram with a specific payload. This radio telegram is called a secure teach-in telegram (abbreviated SEC_TI).
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 6.4.1 Security level format (SLF) The security level format (SLF) defines the security parameters used for communication between two devices. Figure 19 below shows the supported security parameters options encoded in the SLF field.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 7 EMDC commissioning Commissioning is the process by which EMDC is learned into a receiver (actuator, controller, gateway, etc.). The following two tasks are required in this process: ◼ Device identification The receiver needs to know how to uniquely identify this specific EMDC device. This is achieved by using a unique 48 Bit ID (Source Address) for each EMDC device.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 7.1 Radio-based commissioning Radio-based commissioning is used to associate EMDC with other devices by sending a dedicated radio telegram (a so-called commissioning telegram). To do so, EMDC can transmit a dedicated commissioning telegram identifying its relevant parameters according to EnOcean Alliance standard. The transmission of the commissioning telegram is triggered by pressing the LRN button.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 7.2.2 Commissioning QR code format The QR code used in the new product label encodes the product parameter according to the ANSI/MH10.8.2-2013 industry standard. The QR code shown in Figure 20 above encodes the following string: 30S000012345678+Z9E0DE9C25386B6C4F070642E19E03680+30PE6201-K515+2PDA01+S012345567890123 Table 5 below describes the ANSI/MH10.8.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 8 NFC interface EMDC implements an NFC configuration interface that can be used to access (read and write) the EMDC configuration memory and thereby configure the device as described in the following chapters. NFC communication distance is for security reasons set to require direct contact between the NFC reader and the EMDC device.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 8.3 Using the NFC interface Using the NFC interface requires the following: ◼ NFC reader This can be either a USB NFC reader connected to a PC or a suitable smartphone with NFC functionality ◼ NFC SW with read, write, PIN lock, PIN unlock and PIN change functionality This can be either a PC application or an Android / iOS app These options are described in more detail below. 8.3.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 8.4 NFC interface functions For a detailed description about the NFC functionality, please refer to the ISO/IEC 14443 standard. For specific implementation aspects related to the NXP implementation in NT3H2111, please refer to the NXP documentation which at the time of writing was available under this link: http://cache.nxp.com/documents/data_sheet/NT3H2111_2211.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 8.4.2 IDLE state IDLE is the waiting state after a Power-On Reset (POR), i.e. after the NFC tag has been introduced into the magnetic field of the NFC reader. The NFC tag exits the IDLE state towards the READY 1 state when either a REQA or a WUPA command is received from the NFC reader. REQA and WUPA commands are transmitted by the NFC reader to determine whether any cards are present within its working range.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 8.4.6 Read command The READ command requires a start page address, and returns the 16 bytes of four NFC tag pages (where each page is 4 byte in size). For example, if the specified address is 03h then pages 03h, 04h, 05h, 06h are returned. Special conditions apply if the READ command address is near the end of the accessible memory area. Figure 23 below shows the read command sequence. Figure 23 – NFC read command sequence 8.4.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 8.4.8 Password authentication (PWD_AUTH) command The protected memory area can be accessed only after successful password verification via the PWD_AUTH command. The PWD_AUTH command takes the password as parameter and, if successful, returns the password authentication acknowledge, PACK. Figure 25 below shows the password authentication sequence. Figure 25 – Password authentication sequence © 2020 EnOcean | www.enocean.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9 NFC registers The NFC memory is organized in pages (smallest addressable unit) where each page contains 4 byte of data. Several pages with similar functionality form a NFC memory area. 9.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.2 PRODUCT NDEF The PRODUCT NDEF area contains a device identification string using the NDEF (NFC Data Exchange Format) standard that is readable by most NFC-capable reader devices (including smartphones). An example device identification string from the NDEF area of EMDC could be: 6PENO+30S000012345678+1P000B0000004C+30PS6221-K516+2PDA04+2Z01234567891234 +3C31+16S01000000 This NDEF string encodes the parameters shown in Table 7 below.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.4 NFC HEADER The NFC HEADER area contains information about the NFC memory structure and can therefore be used to distinguish between different NFC memory layouts. 9.4.1 NFC HEADER area structure The structure of the NFC HEADER area is shown in Figure 26 below.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.5 CONFIGURATION The CONFIGURATION area allows configuring the device parameters and is therefore the most important part of the NFC memory. Configuration registers larger than 8 bit use big endian format, i.e. the most significant byte comes first. Read or write access to the CONFIGURATION area is only possible after issuing a PWD_AUTH command as described in chapter 8.4.8 using the correct 32 bit PIN code. 9.5.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.5.3 NFC_PIN_CODE The PIN code used to protect access to the NFC CONFIGURATION memory area should be changed from the default value to a user-specific value to avoid unauthorized access to the device configuration. To do so, first authenticate with the current PIN code and then write the new PIN code (32 bit value) to the NFC_PIN_CODE register. 9.5.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.5.5 USER_KEY Each EMDC module is pre-programmed at the factory with a randomly generated 128 bit security key (FACTORY_KEY). This key will by default be used to encrypt and authenticate EMDC radio telegrams when operating in high security mode. In certain applications it might be desirable to assign a different (user-defined) security key (USER_KEY) during commissioning to EMDC.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR The encoding for the SECURE LRN TELEGRAM bit field is shown in Table 9 below. SECURE LRN TELEGRAM Secure LRN telegram 0b00 (Default) Secure LRN Telegram (containing security key) enabled 0b01 Secure LRN Telegram (containing security key) disabled 0b10, 0b11 Reserved, do not use Table 9 – SECURE LRN TELEGRAM bit field encoding 9.5.7 SECURITY_MODE The register SECURITY_MODE identifies the security settings used by EMDC.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.5.8 EEP The EEP register determines the EnOcean Equipment Profile (EEP) used by EMDC for the transmission of data telegrams. Figure 31 below shows the structure of the EEP register. Bit 7 Bit 6 Bit 5 EEP (Default: 0x00) Bit 4 Bit 3 Bit 2 RFU Bit 1 Bit 0 EEP Figure 31 – EEP register The encoding used by the SIZE bit field is shown in Table 12 below.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.5.9 SIGNAL EMDC supports reporting its energy status, the current energy delivery of the harvester and the backup battery status via SIGNAL telegrams as described in chapter 5.2. The type and the transmission rate of SIGNAL telegrams are controlled by the SIGNAL register shown in Figure 32 below.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.5.10 LED_MODE The LED_MODE register determines the brightness of the LED. Figure 33 below shows the structure of the LED_MODE register. Bit 7 LED_MODE (Default: 0x02) Bit 5 Bit 4 Bit 3 Bit 2 RFU Bit 6 Bit 1 Bit 0 LED Figure 33 – LED_MODE register The encoding used by the LED bit field is shown in Table 14 below.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.5.11 FUNCTIONAL_MODE The FUNCTIONAL_MODE register can be used to switch between the different operation modes of EMDC as described in chapter 2.5. Figure 34 below shows the structure of the FUNCTIONAL_MODE register. Bit 7 FUNCTIONAL_MODE (Default: 0x00, OOB: 0x01) Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 RFU MODE Bit 0 Figure 34 – FUNCTIONAL_MODE register The encoding used by the MODE bit field is shown in Table 15 below.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.5.12 STANDARD_TX_INTERVAL EMDC uses a standard reporting interval which can be automatically adjusted based on sensor readings as described in chapter 2.6. The standard reporting interval is set by the register STANDARD_TX_INTERVAL shown in Figure 35 below. The default setting of the standard reporting interval is 120 seconds.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.5.13 OCCUPIED_TX_INTERVAL EMDC can use a different (lower) reporting interval in case motion is detected. The default setting of the reporting interval for the case of detected motion is 60 seconds. This reporting interval is set by the register OCCUPIED_TX_INTERVAL shown in Figure 36 below.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.5.14 THRESHOLD_CFG EMDC can reduce the reporting interval based on the illumination of the solar cell or the illumination of the light level sensor as described in chapter 2.6. The use of these reduced reporting intervals is enabled by the THRESHOLD_CFG register shown in Figure 37 below.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.5.15 LIGHT_SENSOR_CFG EMDC allows the user to select if the reported light level is the one measured by the ambient light sensor or the one measured by the solar cell. Refer to chapter 3.2 for a description of the ambient light sensor and to chapter 3.3 for a description of the solar cell functionality. The selection between these two options is made by using the LIGHT_SENSOR_CFG register shown in Figure 38 below.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.5.16 TEMP_SENSOR_CFG As discussed in chapter 3.4, type and location of the temperature sensor are not suitable for high accuracy temperature measurements. The accuracy can be improved by configuring an offset between measured temperature (measured by EMDC at ceiling level) and the actual temperature. The offset is expressed as 1 byte signed number with 0.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.5.17 SOLAR_THRESHOLD If reduction of the reporting interval based on the solar cell light level has been enabled then the light level threshold is defined by SOLAR_THREHOLD register as shown in Figure 40 below. Bit 15 Bit 14 SOLAR_THRESHOLD … SOLAR CELL THRESHOLD Bit 1 Bit 0 Figure 40 – SOLAR_THRESHOLD register The encoding used by the SOLAR CELL THRESHOLD bit field is shown in Table 22 below.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.5.18 SOLAR_TX_INTERVAL If solar cell illumination-controlled reporting has been enabled and the solar cell illumination is above the defined threshold then the resulting reporting interval will be determined by the register SOLAR_TX_INTERVAL shown in Figure 41 below.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.5.19 LIGHT_THRESHOLD If reduction of the reporting interval based on the light level measured by the light sensor has been enabled then the light level threshold is defined by LIGHT_THREHOLD register as shown in Figure 42 below. Bit 15 Bit 14 LIGHT_THRESHOLD … LIGHT SENSOR THRESHOLD Bit 1 Bit 0 Figure 42 – LIGHT_SENSOR_THRESHOLD register The encoding used by the LIGHT SENSOR THRESHOLD bit field is shown in Table 24 below.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.5.20 LIGHT_TX_INTERVAL If solar cell illumination-controlled reporting has been enabled and the solar cell illumination is above the defined threshold then the resulting reporting interval will be determined by the register LIGHT_TX_INTERVAL shown in Figure 43 below.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 9.5.21 AMBIENT_LIGHT_TEST_RESULT If EMDC has executed an ambient light test as described in chapter 2.5.5 then the result (the measured average light level at the solar cell) will be stored in the ILLUMINATION_TEST_RESULT register shown in Figure 44 below.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 10 Installation recommendations 10.1 Setup instructions Before installing EMDC into its intended location, a sufficient initial charge should be provided to EMDC and its correct operation should be verified. To do so, follow these steps: 1. Place EMDC under bright light (daylight or bright light source) for 5 minutes to provide an initial charge 2. Press the LRN button once so that EMDC will start operation 3.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 10.2 Motion detection Motion detection works based on the temperature difference between a moving object and its environment.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 10.3 Light level measurement EMDC offers the option to measure the ambient light level either via the ambient light sensor or via the solar cell. This can be configured using the LIGHT_SENSOR_CFG register of the NFC interface as described in chapter 9.5.15. By default, the ambient light sensor is used for light level measurements. 10.3.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 10.3.2 Solar cell The solar cell has a much larger area and aperture compared to the ambient light sensor. Therefore, the light level measured by the solar cell is typically more representative of the average illumination within a wider area. Note that the solar cell does not apply a spectral response curve close to the human eye’s perception of ambient light to the received illumination.
USER MANUAL EMDC – ENOCEAN MOTION DETECTOR AND LIGHT LEVEL SENSOR 10.5 NFC configuration EMDC can be flexibly configured for a wide range of application scenarios using the NFC configuration interface as described in chapters 8 and 9.
