With this gas sensor, the presence of smoke or harmful gases in the air can be easily detected. Data coming from the sensor is processed on the Arduino board, which sounds an alarm or takes some other ...

This project implements a smoke detection system utilizing a gas sensor, Arduino microcontroller, DC motor pump, and relay for automated response. Overview: Smoke detection is a crucial aspect of fire ...

In this project, am going to build a smoke detector sensor using Arduino that not only detects the smoke but also reads the level of the smoke in the air and displays it in the PPM.

In this article, I have added three sensors with Arduino UNO and user can choose the required sensor with the help of keypad.
