The Siemens presence and motion detector with an integrated brightness sensor. It is designed for ceiling mounting and communicates via KNX. This device is used to detect the presence of persons in an area and measure the current brightness. It has a range of 20 to 1000 lux for contrast measurement of brightness. With its passive infrared sensor, it can detect motion up to Ø8m. The presence and motion detector features three independent output channels with four commands each in case of motion detection. It also has an integrated 2-level light controller for switching and a constant light level controller for dimming up to five lighting groups. This device can be used in standalone mode or as an extension to cover wider areas. It also has an independent output channel for HVAC applications.
