ATS58-1818 5.8GHz Motion sensor ATS58-1818 User Guide 1.Description ATS58-1818 is a miniaturized 5.8G radar sensor launched by AirTouch Intelligent. The module size is 18 * 18mm and the size is equivalent to a 50 cent coin. The sensor uses AirTouch self-developed radar sensor chip AT5810. Because AT5810 has integrated 5.
ATS58-1818 5.8GHz Motion sensor 3.Input and Output Interface ATS58-1818 can be embedded in end product with three contact PINs, the PIN space is 2.54mm, below is the detail description about the interface: Pin Name Function Note LDO is not attached by default, VCC is 5V, the default power VCC Power supply consumption of the module is 35mA, and the recommended power driving capacity is> 50mA GND Ground PIN OUT Output control Output is 5V TTL by default, could be PWM if needed 4.
ATS58-1818 5.8GHz Motion sensor 5.Radar signal processing AT5810 integrates a microwave circuit and an IF amplifier circuit. After the chip is powered on, the MCU first initializes it through the I2C interface. The configuration parameters include frequency and gain. After initialization, the MCU directly reads the quantized digital IF of the ADC through the I2C Signal, and then output the corresponding inductive control signal according to the characteristics of the intermediate frequency signal.
ATS58-1818 5.8GHz Motion sensor 7.Detected distance The sensing sensitivity of the radar sensor can be configured through the MCU and its maximum sensing distance is 10 meters. The actual sensing distance can be adjusted as needed. The figure below shows the radar detection range in the case of hanging. If the sensitivity is set higher, the detection range will be correspondingly larger.
ATS58-1818 5.8GHz Motion sensor 8.Light-dependent detection According to the Figure 1, there exists light sensor by default and the SDK also enable this function. If light-dependent detection are not necessary, disable on SDK or remove the light sensor. 9.
ATS58-1818 5.8GHz Motion sensor 11. Requirement of FCC KDB 996369 D03 for module certification: 11.1 List of applicable FCC rules: The module complies with FCC Part 15.249 11.2 Summarize the specific operational use conditions: The module has been certified for Fix, Mobile, Portable applications. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. 11.
ATS58-1818 5.8GHz Motion sensor This equipment complies with FCC’s RF radiation exposure limits set forth for an uncontrolled environment. The antenna(s) used for this transmitter must not be collocated or operating in conjunction with any other antenna or transmitter. Note: the host product manuals must include a statement in order to alert the users of FCC RF exposure compliance. 11.6 Antennas: Type Gain Impedance Application PCB type 2.
ATS58-1818 5.8GHz Motion sensor harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: ‐ Reorient or relocate the receiving antenna. ‐ Increase the separation between the equipment and receiver. ‐Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
ATS58-1818 5.8GHz Motion sensor FCC rules that apply to the host not covered by the modular transmitter grant of certification. The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed when contains digital circuity. 11.10 Information on test modes and additional testing requirements: When testing host product, the host manufacture should follow FCC KDB Publication 996369 D04 Module Integration Guide for testing the host products.
