Introduction General description OfficeSense is a workspace utilization sensor solution for LoRaWAN wireless networks to measure occupancy of conference rooms, desks and other office spaces, and for monitoring the indoor office environment. The OfficeSense series consist of a Presence sensor, a Desk sensor, an two different Comfort sensors. The Presence sensor measures room occupancy, temperature and humidity.
Technical information Generic Operating power: EU directives compliance: Network type: Frequency plan: 1.
Comfort Battery type: Range: Recommended installation location: Operating temperature range: Temperature measurement range: Temperature resolution: Temperature accuracy: Relative humidity measurement range: Relative humidity resolution: Relative humidity accuracy: CO2 measurement range: CO2 measurement resolution: CO2 measurement accuracy: Dimensions: Weight Device battery lifecycle Page 5 4 x 1.
Sensor operation The table below describes the different modes of operation and the means of identifying them. The Presence and Comfort sensor have a 2-color LED (green and red) that is used for status indication. Note: Not all operational modes can be identified by the user using the LED. Status redLED Off Status green-LED On Off Off Blinks every 500ms Blinks Off Off Blinks Off On Off Page 6 Description The state after activating the sensor by placing batteries or removing the battery-pull-tab.
Installation guide Presence Sensor and Comfort Sensor Before starting the deployment of the sensors make sure the LoRa network is in place and connected and that the QR codes of the rooms are printed and attached to the rooms. Check Package contents You have received a set of OfficeSense sensors in a box.
Getting the sensors ready The sensors come pre-equipped with batteries. To activate the sensor, you need to remove the plastic pull tab to enable power to the device. To get access to the batteries and the sensor QR code, you need to open the sensor casing. You can open the sensor casing by rotating the base-plate anti-clockwise. This will give you acces to the battery pull-tab and the QR code for registering the sensor to the room.
Mounting the Comfort Sensor The Comfort sensor is advised to be mounted to the wall of the room at a height of approximately 1.80 meters. Provided in the shipping box are strips of double-sided tape which can be used to mount the sensor. Deploying sensors using the double-sided tape 1) 2) 3) 4) 5) 6) 7) Open the Comfort sensor by removing the baseplate (turn anti-clockwise). Stick the tape to the baseplate of the sensor, as shown below. Clean the surface of the wall at a height of 1.
Mounting the Presence Sensor There are multiple options to mount the sensor to the ceiling of the room. Provided in the shipping box are either strips of double-sided tape or special ceiling clips which can be used to mount the sensor. Deploying sensors using the ceiling clip (optional) Note: the ceiling clip can be used with suspended ceiling constructions with metal strips with a width of up to 2.5 cm. 1) 2) 3) 4) 5) Open the sensor by removing the baseplate (turn anti-clockwise).
Presence sensor placement recommendations The sensor needs to be placed right above the working area for the detection of the people working there. Especially in smaller rooms, it suffices to place the sensor in the middle of the ceiling, right above the desk or table to detect everyone sitting around it. For larger rooms, it is recommended to use multiple sensors and spread them evenly across the seating area, like in the figure below.
Desk Sensor The following steps provide an extensive overview of the full installation process and are intended for the building manager and/or installation coordinator. Check Package contents You have received a set of Desk sensors in a box. The box contains the following: Contents of the box Casing Strips of double-sided tape Baseplate PCB (inside casing) The sensors that are shipped are based on your country. Please check if the label on the box matches your region.
Mounting the sensor To mount the devices under desks, you ideally work with two people. Person A: Scans QR codes for correct sensor-todesk mappings. Person B: Attaches the desk sensor devices under the desks. In order to establish an accurate reading, we advise you to install a sensor for each seating on the desk (see picture above). Now you can mount the device under the desk: make sure the orientation of the sensor is right.
Sensor placement recommendations Recommendation 1 Make sure the sensor is placed in the middle of the desk as much as possible. Please refer to the examples below. Sensor placed too much to the right Sensor is not placed straight either Sensor placed in the middle and straight Page 14 OfficeSense sensor installation v1.
Recommendation 2 Place the sensor under the desk at a distance of appr. 35 centimeters / 13,8 inches from the front-edge of the desk. If it is a standing desk, the distance should be as far back as possible which is 55 centimeters / 21.7 Inches. Exceptions: • If there is anything else located under the desk that hinders correct mounting. Then make sure mounting is done as good as possible. Mounting at 35 cm / 13.8 inch is correct Mounting at more than 35 cm / 13.
Recommendation 3 Make sure the sensor is installed according to the picture below. The smoothed front of the sensor should be faced towards the person sitting behind the desk. Additional information The picture below provides some information about the range of the sensor. The example is based on a desk with a height of 80 centimetres, which is not the maximum range of the sensor. Another aspect to take into account is the ‘field of view’ of the motion sensor.
if a desk is not used, the sensor will not likely detect people just passing by. Also when an opposite is used, it is not likely the desk sensor would be triggered by the legs of the person sitting in opposite. The picture below shows the situation with a normal desk at a height of 70 cm. The following picture shows the situation of an elevated or standing desk at a height of 120 cm.

Installing ‘Barcode to Sheet’ application To map or link the sensors to a specific location, e.g. meeting room or desk, they need to be scanned and registered for asset management functionalities in your platform. One way to do this is to use the Barcode to Sheet smartphone app. The use of this app will create a .csv file which can be used to link the sensors to your location in the user application or IoT platform. Prerequisites: A smartphone (iOS or Android) with camera and email capability.
2) After installation, open the app: 3) Click on “+” to create the file to scan and connect the rooms with the sensors. The following screen will appear: 4) Fill in the sheet name with “OfficeSense.. In general, the office 5) 6) 7) 8) Page 19 location is the streetname of the location. Please check your floorplan. Example: OfficeSense.Tilsit (Tilsit is the name of the street address in Paris, France). Fill in 1st column name with “Room”.
You will automatically return to the previous screen where you will find the created file, which is empty for now: Page 20 OfficeSense sensor installation v1.
Registering a sensor with the ‘Barcode to Sheet’ app This process describes how to create a .csv file where the sensors are mapped to the room they are deployed in. 1) Open the ‘Barcode to Sheet’ app on your smartphone. 2) Open the .csv file you have created earlier. The following screen will appear: The next steps describe how to register sensors to a room. 1) Locate a room which you are going to provision with sensors. 2) Locate the QR code of that room (usually near the door).
After finishing all the rooms in your office, you can proceed with the next steps. 1) You can click on the - button to see the contents of the .csv file. 2) Click on the - button and select “email CSV” to send the .csv file to an email address of choice. Add the office location and “sensor to room mapping” as email subject. The data can now be processed in your smart building backend. The presence information will be available in the user app as soon as possible.
Installation procedure reference Preparation checklist Before sensor deployment can begin, check if these items are taken care of first. Make sure the local LoRa network is in place (LoRa gateways are deployed and are connected). Check if QR codes for the rooms have been printed and placed at the rooms, or if other identifiers are available as location reference. Walkthrough this installation manual and procedure with the engineer(s) who are responsible for installation of the sensors.
