About this document
Infrared Motion Detector Circuit Guide by Muhammad Hafeez Kareem is a document available to read on EtoBox.
This circuit uses infrared light to detect motion. It works by sensing the phase difference between infrared light reflected from a static object and light reflected from a moving object. The circuit uses an IC that produces infrared beams. When motion is detected, the output pin of the IC goes high, which can activate an LED or buzzer to indicate an intrusion. Several users asked questions about implementing and troubleshooting the circuit.
