The Light Level Sensor is a C-Bus input device which measures the ambient light levels and converts this information into messages sent across the C-Bus network. C-Bus output units (relays and dimmers) can be configured to respond to such messages, allowing automatic regulation and control of lighting levels.

The C-Bus Light Level Sensor is intended for use in an automatic light level regulation system, and is capable of maintaining a constant illumination level in the range of 40 to 1600 lux (20 to 3000 lux measurable). The Light Level Sensor unit continuously monitors ambient light levels, providing a comparison with the user defined target light level. Control instructions are then subsequently issued to output units on the C-Bus network, altering the light levels as required. eg. RAMP TO LEVEL command issued to a dimmer unit. Sunset switching (ON/OFF) operations are also possible, allowing external lighting to be activated after dark.

The Light Level Sensor unit incorporates filtering and some degree of hysteresis, to suppress noise and compensate for rapid light intensity fluctuations. If the natural ambient light level is such that extra illumination is not necessary, an OFF command is transmitted across the C-Bus network to the appropriately programmed output units.
