PIR Sensor Without Arduino | PIR Security System
In this video, I will show you how to use pir sensor without arduino to control a relay to make a security alarm. Pir motion sensor detect motion and send a signal to its output pin and using that signal we can detect motion and trigger alarm. You can easliy make this pir security alarm with most of components available at home
This is a complete pir security system without arduino uno. You can install it to the main enterance of your home or on the roof. Below is the list of components used in the project
1. HC SR501 PIR Motion Sensor
2. Mobile Phone Charger (+5v)
3. 1N4007 Diode
4. BC547 Transistor
5. 220 ohm Resistor
6. Small Piece of Perf Board
7. Door Bell (220v AC)
8. Relay (5v or 6v)
9. Screw Terminal (2 pin)
