Brightness/Motion Transducer with temperature for ceiling mounting, with changeover contact, 0-10 V

The motion/brightness and temperature sensor BHT-D/A registers movement with an opening angle of 90°-110° over a scope of 360° with a coverage of approx. 10 m, the brightness from 0-1 kLux using a photo-diode and the temperature of the air in the environment from 0…50°C. The retention time of the motions sensor can be freely set between 5 seconds and 15 minutes using a 270° potentiometer. The unobtrusive housing with a clip fastening and reverse polarity protected socket is suitable for the quick assembly in intermediate ceilings. The motion sensor is used for motion dependent control processes, such as e.g. temperature or light control in offices.
