Be in the know about flooding and freezing in your home with the Jasco ZWave Flood and Freeze Sensor. When paired with a compatible hub, this sensor can send out alerts when water levels or temperatures change. The sensor can also communicate with the hub to trigger a variety of smart events. This includes turning on lights, sending alerts to a smartphone, activating an alarm and more. This sensor is universally compatible with ZWave Plus and all previous ZWave generations for easy expansion of any ZWave home automation network. This sensor includes an audible built-in alarm that will sound when water levels or temperature change, so anyone in the area can react to minimize damage. Thanks to its dual function base contacts and detachable probe, this sensor can work in a variety of spaces. The base's recessed contacts work best on flat surfaces, and the included probe extends the sensor's reach so it can be used in wells, sump pump holes and other small spaces.
