Motion and light intensity sensor BHA/A

The brightness and motion sensor BHA/A measures movements in the area of 360° with a range of about 10 m and also the brightness 0-50 klux via infrared sensor and photodiode. The transducer has 4 different measurement ranges (0-0,5 kLux, 0-1 kLux, 0-20 kLux, 0-50 kLux) which can be adjusted by innovative DIP switch technology. In the case of movement, a relay switches, its holding time can be set from 5 sec to 15 min by a 270° potentiometer. The measured brightness value is converted to a linear output signal 0-10 V by the transducer. Alternatively on the device can be made a setting that the motion detection effects in dependence on the measured brightness (light dependent movement detection). The preferred light threshold can be set arbitrarily by an offset controller. The robust housing is specially made for outdoor applications. The motion and brightness sensor is ideal for control processes, such as temperature and lighting control systems in offices, industry etc.
