The Wireless Motion Sensor uses Passive Infrared Sensor (PIR) technology to detect the presence of people by measuring changes in infrared light intensity coming from people moving into the sensor's field of view. Detection events are wirelessly transmitted to nearby Cloud Connectors (gateways) via the SecureDataShot™ protocol. Cloud Connectors relay sensor data to the DT cloud infrastructure. From there, data can be integrated into other services using our REST APIs or viewed directly in DT Studio (web application).
EU and US variants
This sensor is available in two variants, one for the EU and one for the US, due to different certifications, compliances, and wireless communication.

Installation
Detailed installation and planning instructions can be found in the Installation Guideline.
Activation
Detach the mounting plate and remove the battery tabs. Nearby online Cloud Connectors will automatically start to relay data from the sensor to the cloud service.
Mounting
Motion Sensors are designed to be ceiling mounted.
- Mounting option 1, screws (recommended): Attach the mounting plate to the ceiling using the included screws. If necessary, use the wall anchors.
- Mounting option 2, adhesive: Attach the mounting plate to a clean ceiling using the adhesive backing. Add a single screw to the center for extra safety. The adhesive creates a strong bond to the surface and can't be removed and reapplied once placed.
Lock the sensor in place by turning it clockwise on the mounting plate and fasten the included safety screw.
Detection Area
The detection area's size depends on the sensor's installation height.
| Installation Height | Detection Diameter |
|---|---|
| 2.4 meters (8ft) | 9.5 meters (31ft) |
| 3 meters (10ft) | 12 meters (40ft) |
| 3.6 meters (12ft) | 14 meters (45.9ft) |
The maximum installation height possible is 3.6 meters (12 ft), resulting in a detection area diameter of 14 meters (46 ft).
