This high-range Lux Level Sensor measures light intensity from 1 to 200,000 lux with precise digital communication via Modbus RS485. It includes a relay output that can be triggered at a user-settable lux threshold, enabling automated lighting control and energy management. Available in 12V DC, 12–24V DC, and 230V AC power options, the sensor is ideal for industrial lighting systems, smart buildings, warehouses, street-lighting automation, and environmental monitoring.
