Product Description

This ceiling mounted sensor is detecting people motion activity in the sensing range underneath the sensor. The device is wireless and solar-powered, so no batteries are needed under typical light conditions and easiest to mount also in retrofitting.

The unit uses a passive infrared (PIR) sensor technology that permanently records the people activity. After a certain time the number of recorded motion activities (counter value) is transmitted via a radio signal to an IoT space utilization system.

Functional Description

The PIR sensor is permanently active. If any motion is detected within a 1 second measurement cycle time the activity counter is incremented by 1. If any motion has been detected within a 2 minutes transmission cycle time a radio telegram is send with the latest counter value indicating how many increments (motions) have been detected within the latest 2 minutes. If no motion has been detected during the latest 60 minutes an unoccupied message is send (heartbeat signal). The activity counter value is 16 bit and will not be reset after transmission.
