The Wireless Proximity Sensor is optimal for monitoring the activity of a door; Is the door open or closed?
When installing the proximity sensor, place the sensor in the top part of the door frame on the opposite side of the hinge. This placement ensures minimal dust build-up on the sensor and allows the sensor to detect slight door openings.
The sensor can robustly detect objects up to 5 mm from the surface of the sensor.
Avoid the buildup of condensation and ice on the sensor as this may trigger false detections. Also, avoid placement where dust and dirt will set on the surface.
