Abstract
Apparatus and methods for proximity detection include a passive proximity detecting device for detecting humans within a detection area and controlling a controlled device. A sensor includes a plurality of pixels arranged in a substantially contiguous array. Each pixel is configured to detect infrared radiation emitted by an object in a predetermined temperature range within the detection area. In response to detecting the object a detection signal is generated having a signal level proportional to the infrared radiation emitted by said object received by the sensor. A processor in communication with the sensor is configured to receive said detection signal, to derive an object distance and a second object parameter using, a signal level of the detection signal.
