Ubiquiti UniFi Environmental Sensor Water Detection Sensor Temperature Humidity Light SuperLink Battery Power CR123A

Ubiquiti UniFi Environmental Sensor — environmental sensor

A compact and highly functional device for monitoring critical spaces such as server rooms, warehouses or basements. This environmental sensor combines water leak detection, air temperature and humidity measurement and ambient light level monitoring, thus protecting sensitive equipment from damage and ensuring optimal conditions. Thanks to the proprietary SuperLink wireless technology, it achieves reliable communication up to 2 km, even in harsh conditions. With a battery life of up to 6 years on a single CR123A lithium battery and IPX5 protection, it is an ideal solution for long-term deployment.

Advanced environmental monitoring

The device continuously monitors key environmental parameters and immediately warns of critical changes. Water leak detection helps prevent costly damage, while temperature and humidity monitoring ensures optimal conditions for the operation of sensitive equipment. The ambient light monitoring function is ideal for spaces where lighting conditions affect safety or efficiency.

SuperLink Wireless Technology

Thanks to the proprietary SuperLink technology, the sensor achieves wireless communication up to 2 km with a power of 14 dBm, which ensures high transmission reliability even in demanding environments. The 865.1–869.5 MHz frequency range minimizes interference and allows deployment in various commercial environments. Two-color LED status and signal strength indicators facilitate diagnostics and management.

Durability and flexible installation

Thanks to the IPX5 protection, the sensor is resistant to water and dust, which guarantees reliable operation even in demanding conditions. The compact dimensions 53 × 49 × 23.5 mm and low weight 47.8 g allow easy installation. The magnetic holder made of galvanized steel, adhesive tape or screws provide various mounting options, even on smooth or metal surfaces.

Integration with UniFi Protect

The device is fully compatible with the UniFi Protect system, allowing centralized monitoring and management via a web interface or mobile app. The sensor meets NDAA compliance requirements and is FCC, IC, and CE certified, ensuring safe use in commercial environments worldwide.
