The Z-Wave 3 in 1 sensor is designed with three detection sensors: 1. Water/ Flood 2. Temperature 3. Humidity The detector can be used as a security device or home automation device. When the detector is cooperated with security appliances, the detector is acting as a security device by detecting flood, e.g. next to a leaking washing machine. Additionally high temperature and humidity detection can be defined as trigger for alarm signals.   Besides the water sensor can be used monitoring water level in filled vessels, e.g. a tank, to inform in case of low water.
