This project shows a simple and effective Gas Leak Controlled Fan Circuit for home safety. When gas is detected by the sensor, the circuit automatically activates a relay and turns ON the exhaust fan to remove harmful gas from the area.
The circuit uses a gas sensor module, BC547 transistor, 5V relay, diode protection, and basic components. It is a low-cost and practical safety project that can help prevent accidents caused by LPG or other gas leaks.
🔹 Automatic fan activation on gas detection
🔹 5V relay switching
🔹 Transistor-based driver circuit
🔹 Simple and easy to build
This project is perfect for beginners and electronics students.
Check the pin connections carefully before powering the circuit.
