This project is designed to detect gas leakage using an MQ-2 gas sensor and alert users through a red LED light and a buzzer. The system is controlled by an Arduino Uno microcontroller, making it easy ...

Gas leaks can pose serious safety risks, especially in homes, kitchens, and small commercial spaces. In this project, you'll learn how to build a simple and budget-friendly gas leakage detector using ...

In this project, we will build Gas Leak Detection & Alarm System using MQ2 Gas Sensor and Arduino UNO Board. The MQ2 sensor is a versatile gas sensor capable of detecting a wide range of gases as well ...

To build this LPG gas leakage detector using arduino uno, we used a LPG gas sensor module to detect LPG Gas. When LPG gas leakage occurs, it gives a HIGH pulse on its DO pin and arduino continuously ...

For testing, refer to Fig. 7. After uploading and assembling the components, power on the circuit, including Arduino and other components, using a 5V adaptor. When gas leakage is detected, it ...
