In this project, we will create a smoke detector using Arduino. The detector will detect the smoke and will notify the user through the buzzer and red LED if the smoke density is above the safety limit.

Apr 30, 2024 · Arduino boards can read digital & analog inputs from the sensors and The MQ2 smoke sensor is sensitive to smoke gases like LPG, Butane, Propane, Methane, Alcohol, Hydrogen. In this article, We will learn how can we make a Smoke Detector Alarm using Arduino.

May 14, 2021 · If you have access to an Arduino Uno board, you can tweak it to design your own homemade smoke detector. Adding a simple MQ2 gas detecting sensor module to the project makes it a combined smoke + gas detector device.

May 5, 2016 · This guide shows how to build a smoke detector that beeps when it detects flammable gas or smoke. The MQ-2 Gas Sensor. The MQ-2 smoke sensor is the one in the following figure: The MQ-2 smoke sensor is sensitive to smoke and to the following flammable gases: LPG; Butane; Propane; Methane; Alcohol; Hydrogen

In this Smoke Detector Circuit with Arduino, we have used a MQ2 Gas Sensor to detect preset smoke in the air. A 16x2 LCD is used for displaying the PPM value of Smoke. And an LM358 IC for converting smoke sensor output into digital form (this function is optional).

Apr 16, 2022 · In this project we build Smoke Detector using Arduino and MQ2 Gas Sensor. Here, the MQ2 Gas Sensor is used to detect Smoke. When the gas is detected the LED glows and Buzzer makes sound. Also an alert message is displayed on the 16×2 LCD Display. Everything is controlled using Arduino UNO.

Nov 8, 2023 · Smoke detector or a fire alarm system can be built just using the gas sensors such MQ135 gas sensor or MQ2 gas sensor, without microcontroller. for this project, we will be using MQ135.

Jun 11, 2018 · Arduino board I'm using is Arduino UNO. I have also designed an LPG Gas Leak Detect using Arduino using this MQ2 Sensor. So, let's get started with How to design Smoke Detector with Arduino & MQ2 Sensor.

Apr 13, 2024 · In this tutorial, I’ll show you how to interface an MQ-2 Smoke sensor with Arduino Uno. Results of the smoke sensor are displayed over the serial monitor. When you need to monitor a fire initialization, Smoke Sensor is the best way to detect the percentage of carbon monoxide (CO) in parts per million (PPM).

Jun 5, 2019 · Build your own gas and smoke detector that can read and display smoke levels using the MQ-2 and an Arduino. This tutorial walks you through building a smoke detector that not only senses smoke and other harmful gases in the air but also reads and displays smoke levels in PPM (parts per million).
