The PoE•X Water Detect Plus Sensor detects either the presence or absence of water. For example a leak-prone pipe within a facility. You may want to know when there is no water present, or you may need to know when the pipe begins leaking so it can be quickly repaired. This flexibility makes Monnit’s Water Detect Sensor the best way to monitor water presence in your environment. The sensor will remotely assess and regularly report on activity, instantly notifying you the moment change is detected.

The Power-over-Ethernet (PoE) Sensor products measure various conditions (environmental, power, access). All devices come with flexible settings — including notifications, alerts, reports, and maps — can be customized in the iMonnit online sensor management interface.

No PoE infrastructure in your building? Plug the PoE•X Sensors into your Ethernet network and then power the sensors with the optional AC power supply.
