The SIMPLEST Motion Sensor Circuit using BC547 | PIR Sensor Without Arduino

In this video I have shown you how to make a simple circuit using a PIR Sensor and a BC547 transistor. This circuit runs on 5 volts and is very easy to make. I hope you'll like it and try to make it yourself.

Components used in this circuit:

PIR sensor

BC547 transistor

5mm LED

USB cable
