Alarm system using pyroelectric infrared sensors for measuring distance and alarming
A novel and reliable alarm system consists of a pyroelectric sensor, an infrared len, amplified module, microcontroller and alarm module. According to different signal peak-to-peak values which person at different distances causes the system, the system can get the distance of the person and decide whether the system sends the information to computer. Before working the system needs to calibrate the persons characteristic values at different distances using the method described in this paper.
infrared sensor alarm system distance measure.
