The code for the Arduino mq-2 gas sensor module is very simple and easy to understand. We are just reading the analog data out of the sensor and changing the brightness of the LED according to the ...

MQ2 gas sensor is also sensible to LPG, Alcohol, and Methane etc. This Smoke Detector can be easily built on Bread Board or Dot Board but we have decided to build this as an Arduino Shield on PCB.

This project presents a fire-fighting robot designed to autonomously detect and extinguish fires. The robot utilizes Arduino as its microcontroller, incorporating various sensors and actuators to ...

LPG is an alternative fuel used for daily use. Due to its low cost and ease of installation. This article covers an Arduino-based gas detection system that uses an Arduino UNO R3 board and gas sensors ...
