The NCD Industrial IoT Wireless Contact Closure Sensor acts as a wireless push notification transmitter, alerting users when water is detected. It includes a 3-conductor, 1-feet probe attached to the main box, transmitting signals upon detecting input changes. Ideal for security applications, it reliably sends long-range wireless dry contact transmissions.

Powered by 4 AA batteries, it offers up to 500,000 transmissions or up to 10 years of battery life, depending on conditions and transmission intervals. The device can transmit up to 2 miles with included antennas or up to 28 miles with high-gain antennas. It sends alerts upon detecting open or closed contacts and periodically updates input status and battery level.
