Sensaphone Wireless Humidity Sensor - environmental monitoring sensor

The Sensaphone Wireless Humidity Sensor is designed to work exclusively with the Sensaphone WSG30. This sensor includes a built-in radio transmitter and humidity sensor element for monitoring humidity wherever the device is installed. The sensor comes with two AA alkaline batteries which will power the sensor for up to two years. An optional plug-in power supply is also available. The batteries become a backup if main AC power fails.
