IR Motion Sensor

Description

This circuit is an infrared motion detector using an NE555 timer IC for AC load control and an IR sensor module for sensing motion. Some key components of the circuit are a BC547 NPN Transistor which functions as a switch, an op amp for voltage gain, a single pole double throw relay, as well as the NE555 integrated circuit and IR sensor module discussed earlier. Additionally, LEDs, resistors, wires and capacitors were used. Motion detectors are common and useful in everyday life. This is just one example of how to build one.
