The motion/brightness and temperature sensor BHT-D/A measures movements in the area of 360° with a range of about 10 m by an infrared sensor, brightness from 0-1 kLux by a photo diode and the temperature from 0...+50°C. The holding time of the motion detector can be defined by a 270° potentiometer from 5 seconds to 15 minutes. The unobtrusive housing with snap fastening and torque/pole-protected plug is suitable for quick mounting in suspended ceilings. The motion sensor is ideal for control processes, such as temperature and lighting control systems in offices.
