Monnit Wireless Dry Contact Sensor - AA Battery Powered

Monnit 1 Wireless Dry Contact Sensor - AA Battery Powered

The Monnit Wireless Dry Contact Sensor detects when there is contact between the two wired end points. It can easily be integrated into existing switches or contact plates. When the sensor detects contact between the two end points a wireless communication is immediately sent to the gateway. The gateway will immediately attempt to securely send the message to iMonnit, or other approved data services.

The sensor can be configured to detect both closed and open loops, alerting if contact is made or broken and on state changes.
