The MQ2 sensor is a versatile gas sensor capable of detecting a wide range of gases as well as smoke. This initiative is centered on creating a mock-up of a gas leak detection system utilizing an ...

This code helps interface the MQ2 gas sensor with an Arduino microcontroller. The MQ2 gas sensor detects the levels of LPG, CO and smoke in air. This project can be used in various applications like ...

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 ...

MQ-5 Gas Sensor with Arduino UNO – Connection Diagram Now that we understand how the MQ-5 gas sensor operates, we can connect all of the necessary wires to an Arduino Uno and test it out.

Gas leaks are one of the big problems in the industrial sector, even starting to spread to other sectors. One of the solutions to reduce losses due to gas leakage is to detect it early when there is a ...

In this project, we are going to use MQ-135 sensor with Arduino to measure the CO2 concentration in PPM and display it on OLED.
