The Milesight EM300-SLD watches one point for a leak: a drip tray, pump base, valve, water heater or under a sink. The stainless steel spot probe sits on the floor on a 1.5 m cable, and the transmitter mounts on the wall above.
Why pick it
- Alarms when conductive liquid reaches 5 mm at the probe.
- Reports temperature and humidity too, so one unit covers a plant room or comms cupboard.
- IP67 with a replaceable 4000 mAh battery. Milesight D2D can switch another Milesight device, such as a valve controller, with no gateway.
To cover a strip of floor or a pipe run rather than a point, use the EM300-ZLD with its 3 m sensing rope.
Works with any standard LoRaWAN gateway and network server, such as the Milesight UG65 indoors or the UG67 outdoors, with alerts and dashboards on IoT Factory.
