Advances in technology have led to the development of various sensing devices such as on-body and health-care monitoring that can integrate from different sources and can initiate actions or trigger alarms when needed. This paper developed a sensing module of standing and moving human body using a shutter and a pyroelectric infrared (PIR) sensor. The module consists of Fresnel lens, PIR sensor, interface circuit of the PIR, microcontroller unit (MCU), and light emitting diode (LED) as an alarm indicator. The principle for standing human body is to chop the thermal heat of human body utilized by the camera shutter. The human sensed signal is the controlling part of this algorithm, the detected interruption serves as its function. By merging the whole apparatus including the print circuit board (PCB), the developed product of this proposed sensing module can replace the commercially available detector. Experiment results show that sensing distance is about 7.0 meters with a sensing angles of around 110 degrees at room temperature. In these conditions, the sending ratio is 100% and the module’s power dissipation is rated as 100 mW.
