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.

Oct 26, 2019 · This project can detect gas leaks, fire and smoke and when powered by a nine volt adapter can act as a gas leak detector for kitchens. This project can be used to detect gas leaks and also detect fire in the kitchen or any other place in your house.

Feb 16, 2021 · Build a simple DIY Arduino Smoke Detector with MQ-2 Gas/ Smoke sensor. ... I2C 16x2 Arduino LCD Display Module. Apps and platforms. 1. Arduino IDE. Project description. Code. Sample code. arduino. You can use this code to obtain the analogue readings from the MQ type sensor module.

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).

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.

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.

May 5, 2016 · This guide shows how to build a smoke detector that beeps when it detects flammable gas or smoke. 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: The resistance of the sensor is different depending on the type of the gas.

Nov 8, 2023 · Step by step guide to build your own smoke detector system using Arduino and MQ135 gas sensor, explore two ways to build a fire alarm for your safety. Hello guys, today we will build a smoke detector system, in two different ways with the most simple and easy tutorial. In our world, safety takes prime importance, there's no room for compromise.

Gas and Smoke Detection: Utilizes the MQ2 sensor to monitor gas and smoke levels. Visual Display : Displays real-time sensor readings on an LCD1602 screen. Warning System : Activates an LED and a buzzer when gas or smoke levels exceed a safe threshold.

Feb 14, 2023 · But you can create your own smoke detector alarm system using Arduino. It is suitable for detecting NH3 (ammonia), nitrogen oxide, sulfide, alcohol, benzene, smoke, carbon dioxide, etc. If you want to do more advanced projects like precise gas measurement etc, you need to calibrate them first.
