Flood Sensor

The flood sensor measures conductivity and indicates whether the sensor is dry, damp or completely immersed in water. When water or other conductive liquid is present, a tiny electrical current flows between the metal contacts on the sensor. The sensor will not give false alarms due to condensation or high humidity. This unit connects to an analog input on the environmental monitor. A CCAT analog-to-digital converter may be used to connect to a digital port
