Multiple sensors in one compact device
The Ubiquiti UniFi Environmental Sensor combines multiple functions in one small housing. You monitor temperature, relative humidity, ambient light and especially the presence of water where it indicates leakage. The sensor has contact points on the bottom for detecting stagnant water and contact points on the top for detecting drops or condensation leakage. This allows you to monitor both floor level and overhead pipes or equipment. You can connect an external leak detection probe via the 3.5mm AUX port for a larger detection area.
Reliable SuperLink connection up to 2 kilometers
Thanks to SuperLink technology, the sensor communicates with your UniFi SuperLink Gateway over a range of up to 2 kilometers. This makes it suitable for large buildings, underground spaces or locations where traditional WiFi connections are not stable enough. The sensor operates energy efficiently and remains in a low-power sleep mode until a reporting moment or event occurs. This allows the CR123A battery to last up to 5 years on standard settings and up to 6 years with less frequent reporting.
Weatherproof and flexible environmental sensor
With an IPX5 rating, the Ubiquiti UniFi Environmental Sensor is protected against water jets and humid environments. You place it wherever you want with the included adhesive strip, magnetic holder or screw mounting. The compact design fits effortlessly in server cabinets, above ceiling plates or next to pipes. Thanks to the plastic housing and galvanized steel mounting plate, the sensor is robust enough for professional installations.
Full integration into UniFi Protect
You connect the sensor to Ubiquiti UniFi Protect, where you can set events and warning messages entirely according to your wishes. You will receive notifications via push notifications or webhooks in case of water leakage, abnormal temperatures or moisture values and light changes. Pressing the side button temporarily wakes the sensor from sleep mode for immediate synchronization and identification within UniFi Protect. This is useful for installation or troubleshooting.
