The body infrared sensor for control of lighting is a body presence detector used in modern lighting systems. In contemporary lighting systems, it is incorporated as an infrared sensor which controls the lighting by sensing human bodies. The presence of a person in the range detected by the sensor activates lighting while moving away deactivates it. In addition to energy savings, this device enhances the operational life and dependability of the lighting systems and of the whole system. The application of this sensor covers almost all walks of life, residential, office and industrial.
