About Ubiquiti Environmental Sensor, Battery-Powered SuperLink Sensor Detects Water Leaks, Temperature, Humidity, Ambient Light.

The Ubiquiti Environmental Sensor is a small battery-powered sensor that keeps an eye on the conditions in your server room, comms cupboard, storeroom, or anywhere else a leak or heat spike could cause grief. It detects water leaks, temperature, humidity, and ambient light, then sends alerts straight to UniFi Protect so you can act before a small problem turns into an expensive one.

Key Features

  • Four Sensors in One — Temperature, humidity, ambient light, and water sensing all in a single compact unit, so you get the full picture without mounting a pile of gear.
  • Water Leak Detection — Built-in water sensing contacts pick up moisture on the surface, and a 3.5 mm AUX jack lets you add a separate leak probe to cover more ground.
  • Long-Range SuperLink — Ubiquiti's proprietary SuperLink wireless reaches up to 2 km (1.2 mi), so you can monitor distant sheds, basements, and outbuildings without running cable.
  • Six-Year Battery Life — A replaceable 3V CR123A lithium battery lasts up to six years, meaning you can set it and forget it.
  • IPX5 Weatherproof Build — A polycarbonate case rated IPX5 handles water jets and splashes, so damp spots are no drama.
  • Flexible Mounting — Adhesive, magnet, and screw mounting with a galvanised steel mount means you can stick it almost anywhere in seconds.
