Wireless Lux Light Meter – Ambient Light Intensity Sensor (0–82,000 Lux)
Monitor light levels with precision up to 82,000 lux. Ideal for smart lighting, energy management, and environmental monitoring.
Product Description
The ALTA® Wireless Lux Light Meter is a high-performance sensor designed to measure ambient light intensity across a wide range of environments. With a measurement range of 0 to 82,000 lux, it’s ideal for applications requiring accurate light level monitoring, from office buildings and greenhouses to museums and industrial facilities.
Equipped with a high-sensitivity photodiode, the sensor delivers precise readings with 0.01 lux resolution, making it suitable for light-critical operations. Users can set customizable thresholds to trigger alerts when light conditions fall outside desired ranges—perfect for optimizing lighting efficiency, protecting sensitive materials, or ensuring regulatory compliance.
⚠️ Note: Requires a compatible Monnit gateway and may require software. Visit the Gateway & Software section or explore our pre-configured kits for setup.
