Sensing module for standing and a moving human body using a shutter and a PIR sensor was developed. The principle for a standing human body is chopped by utilizing the human body’s thermal heat by the use of a shutter. The human sensing signal is the controlled part of the proposed algorithm the detected interruption serves as its function. Experiment results show that sensing distance is about 7.0 meters and sensing angles is around 110° at room temperature. In these conditions, sending ratio result is 100% and the power dissipation of the module is rated at 100mW. By merging the whole apparatus and PCB, the developed product sensing module can replace the commercially available detector for a moving human body.
