ThingseePRESENCE

Figure 1: ThingseePRESENCE is a wireless sensor for measuring people presence through your facility.

Thingsee PRESENCE gives you information on people movement in your spaces. You can use the sensor for facility management, workspace occupancy and visitor count. ThingseePRESENCE uses a passive infrared sensor to detect a heat source movement (human, animal, etc) in an area. The indicative count of detections is reported to the cloud. The device has Wirepas connectivity and requires Wirepas-enabled gateway for cloud communication.

Figure 2: ThingseePRESENCE is almost as small as a match-box.

BLE Connectivity

  • Unofficial release available on request

Things to note when planning the service

There’s always delay from measurement to alerts: measurement results are sent in predefined intervals (e.g. 1 minute) and some time is taken for the data to travel through the network and processed in the cloud service.

Things to note when planning the installation

ThingseePRESENCE is based on a passive infrared sensor (PIR) and it detects the changes in heat sources (e.g. moving humans). If the temperature difference between the moving source and the surrounding environment is small, the reliability is significantly reduced.

Visitor counting is always affected by many external elements. E.g. the following factors affect:

  • Width of the doorway
  • People walking right next to each other
  • Standing / slowly moving lines of people
  • Cleaning and maintenance situations
Figure 3: Sensor is for indoor use only
Figure 4: Sensor is more sensitive to movement across sensor detecting area than towards sensor.
Figure 5: Sensor can measure the only movement inside detecting area eg. it is not a volumetric sensor.
Figure 6: Place sensor 2.5m/8ft above floor level and avoid locations where pets can climb to a middle part of detection field. Reduce sensitivity in these cases.
Figure 7: To cover all required movement, use multiple sensors in a big room.
Figure 8: Placing sensor to the corner enables better detection area coverage.
Figure 9: Sensors can be placed either to the wall or to the roof.
Figure 10: If the sensor is placed to the roof in the low height space, sensors should be placed close enough to each other to cover the detecting area.

Things to avoid when planning the installation

Figure 11: Nearby heating or cooling devices and/or vents. Especially direct warm or cool air blow towards sensor can cause false functionality.
Figure 12: Direct or indirect sun light.
Figure 13: Nearby halogen lamps or similiar hot surface lamps.
Figure 14: Placement of nearby radio equipment like Wifi routers or any other similar high power RF transmitters.
Figure 15: Places where door or similar object can block required detection area.
Figure 16: Attachment to surfaces which can vibrate as it may cause false functionality.

Installation

Figure 17: A detection area is cone-shaped with a possibility to alter the area by using different domes.

Visitor Counter Dome

Figure 18: Visitor counter dome. Detection beam can easily be adjusted with the separate Adjustment Dome. It is easy to install and makes the detection beam more accurate.

Installation

Figure 19: Dome installation. Dome can be attached with screws to ensure robust installation. Use correct screw type!
Figure 20: When using only attachment clips, screw attachment parts can be cutted off. Do not damage attachment clips while cutting!
Figure 21: Beam-adjusting dome limits the detection area and makes the detection in the preferred area more accurate. With the dome, the detection area is narrow related to the long side of the ThingseePRESENCE sensor.
Figure 22: Detection area shape related to three most common installation distance.
Figure 23: Sensor assembly to the roof. Install Thingsee PRESENCE sensor to the roof inside of the room. Place sensor in the middle of the door opening and 5 to 10 cm distance from the wall. Make sure that there is no blocking objects between the sensor and the area wanted to be detected.
Figure 24: Sensor assembly to the door opening. Install Thingsee PRESENCE sensor to the top of the door opening in the middle of the door opening. Make sure that there is no blocking objects between the sensor and the area wanted to be detected.

Desk Occupancy Dome

Figure 26: Detection beam can easily be adjusted with the separate Adjustment Dome. It is easy to install and makes the detection beam more accurate.
Figure 27: Dome can be attached with screws to ensure robust installation. Use a correct screw type!
Figure 28: When using only attachment clips, screw attachment parts can be cutted off. Do not damage attachment clips while cutting!
Figure 29: Thingsee PRESENCE is possible to install under the table to detect usage of the working place. Sensor sensitivity should be decreased to avoid unwanted detections outside of the working place.
Figure 30: Install Thingsee PRESENCE under the table cover as middle as possible. If there are objects under the table, place the sensor near to object on the user side of the object. Make sure there is 50 mm gap between ThingseePRESENSE and object to ensure maintenance work.
