TR-972 is a microwave  sensor based on  Doppler .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.

TRIS -972  is mainly used in early warning for break-in Typical application:

1、 important financial district (ATM)
2、 small size shop
3、 residential buildings
4、 secret department
5、 storage
6、 school

Control following equipment component

1、 alarm, siren
2、 short message warning system
3、 smart terminal
