The Lux Level Sensor is a high-range light intensity measurement device designed for industrial, commercial, and smart-building applications. It measures illumination levels from 1 to 200,000 lux with 12-bit resolution, ensuring accurate and stable readings across very low and very high light conditions. The sensor supports analog output (0–10V / 4–20mA) for easy integration with PLC, BMS, EMS, data loggers, and automation controllers. It also includes a relay output that can be triggered at a user-settable lux level, enabling automated lighting control, alarms, and event-based actions. Available in 12V DC, 12–24V DC, and 230V AC options, this sensor is suitable for a wide range of environments such as warehouses, production plants, street-lighting automation, greenhouses, and energy-monitoring systems.
