The Ubiquiti USL-Environmental is a versatile, battery-powered environmental monitoring sensor that enhances your UniFi Protect or related Ubiquiti ecosystem with robust, continuous awareness of key conditions across indoor and semi-outdoor spaces. Designed around Ubiquiti’s proprietary SuperLink wireless technology, this device delivers reliable long-range connectivity with very low power consumption, making it ideal for deployment in areas where consistent status updates matter but frequent maintenance isn’t practical.

At its core, the USL-Environmental unit combines multiple sensing capabilities into one compact, rugged package. It continuously monitors ambient temperature and relative humidity to help ensure comfort, stability, or compliance in sensitive locations like server rooms, offices, basements, plant rooms or storage areas. An integrated ambient light sensor adds context to environmental changes, while dedicated water-leak detection helps you react swiftly to potential flooding or moisture issues before they escalate into costly damage.

Built for durability and long-term service with minimal upkeep, the sensor houses a replaceable CR123A lithium battery that can provide up to six years of life under typical usage, and is enclosed in an IPX5-rated polycarbonate case that withstands splashing water and everyday environmental stress. Mounting flexibility—including adhesive tape, magnetic attachment, or screw fixtures—means you can place it almost anywhere you need discreet, reliable monitoring without clutter.

The USL-Environmental integrates seamlessly with the UniFi Protect interface through web or mobile apps, allowing you to view real-time sensor data and receive alerts alongside your other smart devices. Whether you’re safeguarding critical infrastructure or simply want dependable environmental insight, this multisensor brings proactive awareness to your networked environment with minimal fuss.
