The DHM-303T Contact Sensor can be used to detect whether a door or window is open or closed. You can use
this to provide security for windows, or to monitor entry and exit through a doorway, and can be used in tandem with
other sensors and keypads to monitor and control access to an area.

The DHM-304T Motion Sensor can be used to detect motion in an area. You can change the sensor's motion detec-
tion sensitivity to help you nd the right balance to detect movement without false alarms.
