LLR-BAC sensors have been designed to measure Light Level (LUX) in the room spaces. The LLR sensors also monitor for occupancy via infra-red detection.. The Modbus RTU Light and Occupancy sensors have linear 0..10V signals outputs relating to light level and optional temperature. The units also have two digital inputs, a resistive input and two digital outputs that can be used to control and integrate other devices in the room space.

The LLR-MOD Modbus light and occupancy sensors have built-in Modbus RTU communication that allow Modbus Masters such as building management or home automation systems to measure the light levels and check the room space occupancy.

LLR-MOD Modbus Light Level and Modbus Occupancy sensors can be installed on wall surface or on a wall mounting box in dry indoor environment. The LLR-MOD Modbus light sensors come with a number of options such as display, push buttons and temperature measurement.

The LLR-MOD Modbus light sensors can also operate as light level and temperature controllers modulating analogue outputs of the sensor. These features allow combining measurement and accurate control of the room space.
