#SecurityAlarm #LoopBreakAlarm #HomeSecurity In this video, I show you how easy it is to build a simple security alarm circuit at home using very basic and low-cost electronic components. This loop break security alarm circuit works on a simple logic—when a thin wire breaks, the alarm turns ON automatically. How to make security alarm circuit make at home
This project uses only:
One BC547 NPN transistor
One 100k ohm resistor
One buzzer
A 12V DC battery or power supply
No ICs, no complicated wiring, and no expensive parts!
This circuit is perfect for beginners, students, and DIY electronics lovers.
🔧 How it works:
A very thin wire is connected between the base and emitter of the transistor. When the wire is intact, the circuit stays OFF.
As soon as someone passes through and the wire breaks, the transistor activates and the buzzer sounds continuously, alerting you instantly.
🏠 Applications:
Home security
Room door alarm
Window security
Low-cost intrusion alarm
DIY electronics projects
This is a low-budget, easy-to-make, and effective security solution that anyone can build at home.
