Apr 16, 2022 · In this project, the Arduino UNO plays a crucial role as the brain of the system. The Arduino UNO receives input from the MQ2 gas sensor, which detects smoke and other gases, and based on that input, it controls the red and green LEDs and the 16×2 LCD display.

Feb 16, 2021 · In this post, I will be explaining you about making a DIY Arduino Smoke detector with MQ-2 Gas/ Smoke sensor. If you are unfamiliar with the MQ-2 Gas sensor, please read this short and simple introduction about the sensor before you move on. For this project, you will be needing the LiquidCrystal_I2C library and the Wire library.

Oct 7, 2020 · 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 …

Aug 22, 2022 · In this project, we have designed Arduino Smoke Level Detector using MQ-135 Sensor for measuring the level of smoke in the environment. Simply we have interfaced MQ-135 Gas Sensor module with Arduino and 16*2 LCD module for display.

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 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.

The Smoke Detector Project is built using an Arduino Uno board, an MQ-2 smoke sensor, a Bluetooth module, a 16x2 LCD display, LEDs, and a buzzer. This project is designed to detect smoke in the environment and alert the user via the LCD display, LEDs, and buzzer.

4 days ago · In today's world, early detection of fire hazards is critical to ensure the safety of homes, offices, and industries. In this project, we will build a Smart Smoke and Fire Alarm System using an Arduino Uno, an MQ-2 Smoke Sensor, a Buzzer, and an LCD Display.This system will detect smoke or gas leaks and immediately alert you through sound and a visual message.

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).
