## Long description

The Ubiquiti USL-Environmental is a high-precision multisensor engineered to provide comprehensive monitoring of environmental conditions. This versatile device tracks ambient temperature, relative air humidity, and ambient light levels, while also functioning as a reliable water leak detector. Designed for durability, the sensor features an IPX5-rated enclosure, making it suitable for deployment in various indoor and outdoor settings where environmental stability is critical.
Advantages
This multisensor offers a robust solution for maintaining optimal conditions in sensitive areas. Its multi-functional design eliminates the need for multiple separate devices, as it integrates temperature, humidity, light, and leak detection into a single compact unit. The IPX5 rating ensures that the device remains protected against water jets, providing peace of mind when installed in environments prone to moisture or accidental spills. Furthermore, the use of a high-quality CR123A lithium battery ensures long-lasting, consistent performance, allowing for reliable data collection without the need for frequent maintenance.
Suitable for
Monitoring server rooms and data centers for temperature and humidity fluctuations.
Detecting water leaks in basements, utility rooms, or near plumbing fixtures.
Tracking ambient light levels in smart home or office automation systems.
Maintaining environmental standards in storage areas or greenhouses.
When it may not be suitable
This device is not intended for use in environments where it will be fully submerged in water, as the IPX5 rating only covers protection against water jets. Additionally, because it utilizes a wired connectivity technology, it may not be suitable for locations where running physical cables is impractical or impossible.
Key specifications
Measuring functions: Ambient temperature, relative air humidity, ambient light, and water leak detection
Connectivity: Wired
Power source: 3V CR123A lithium battery
Ingress protection: IPX5
Dimensions: 53 mm width, 23.5 mm depth
Weight: 47.8 g
How to use
To begin using the Ubiquiti USL-Environmental, ensure the device is placed in the desired location where environmental monitoring is required. Connect the sensor to your existing monitoring infrastructure using the appropriate wired connection. Once connected, insert the CR123A lithium battery into the designated compartment. The device will begin collecting data immediately, which can then be viewed and managed through your compatible smart monitoring system interface.
What to consider before purchase
Verify that your current monitoring system supports wired sensor integration.
Ensure the installation site is within reach of your cabling infrastructure.
Check that the IPX5 rating meets the specific moisture exposure requirements of your intended environment.
Usage recommendations
For optimal performance, periodically check the battery status and ensure the sensor surface remains free of dust or debris that could obstruct light or humidity readings. If used for leak detection, place the sensor directly on the floor surface in areas most susceptible to water accumulation.
