TR-972 is a microwave motion sensor based on Doppler priciple.Its planar antenna emits extremely low power electro-magnetic wave and Receives their echo. The sensor detects the change in echo in its detection zone，the microprocessor then triggers the relay to output the signal to application. It can be apply on public area like corridors, side walk, warehouse and big office areas etc.

Function
Body activities monitor finally confirms out-put signals by surveying body moving distance per hour and a series of combinatorial algorithm

Notice

According to the working principle and property of the monitor, we must avoid large area metal block between the objects which need to be monitored and the monitor, or the sensitivity will be influenced seriously. When installed, the monitor should be put at the side without metal.
