The room brightness sensor with selectable measuring ranges and color filter to adjust the sensitivity similar to the human eye captures the brightness indoors. Designed for controlling lighting or sun protection systems. The device can be mounted directly on the wall, on a flush-mounted box or in conjunction with a frame for surface-mounting (see accessories).
