In this project, we will learn how to create a smoke detector using Arduino. This will help us detect the intensity of gases.

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 · In this article, We will learn how can we make a Smoke Detector Alarm using Arduino. When the MQ2 Gas Sensor will detect the smoke level high, the red led will glow and the buzzer will start. Components Required. Arduino UNO -> A microcontroller board based on the ATmega328P; MQ2 Gas Sensor -> Which detects the level of smoke

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).

Dec 22, 2020 · This blog is based on Smoke Detector System Using MQ2 Gas Sensor and Arduino. Here we will discuss Introduction to Smoke Detector System, Project Concept, Block Diagram, Components Required, Circuit Diagram, Working Principle, and Arduino Code.

Feb 25, 2022 · Because in this tutorial we are going to interface MQ2 Gas Smoke Sensor with Arduino UNO. MQ2 gas sensors are employed to effectively detect smoke, alcohol, LPG, carbon monoxide, etc in the environment.

Thus, this tutorial is about interfacing ” MQ-2 Gas/Smoke Sensor with Arduino UNO”. The MQ-2 smoke sensor is the metal oxide semiconductor sensor. Hence, also recognized as a chemiresistor. Its working principle is based on the resistor. When it detects smoke or fire, the value of its resistance changes. That’s how the gas or smoke gets detected.

Dec 19, 2020 · This blog is based on Air Pollution Monitoring System using Arduino and MQ135 Air Quality Sensor. Here we will discuss Introduction to Air Pollution Monitoring System, Project Concept, Block Diagram, Components Required, Circuit …

May 14, 2021 · Adding a simple MQ2 gas detecting sensor module to the project makes it a combined smoke + gas detector device. Just using a few easy steps, you can perform safety monitoring as well harmful gas detection. Below we present a simple project description of an Arduino Uno device being used in this manner.

Connect the MQ2 gas sensor to the Arduino Uno R3 following the circuit diagram. Upload the arduino_code.ino file to the Arduino Uno R3 using the Arduino IDE or compatible software. Customize the code to add advanced features or modify the alarm thresholds as per your requirements. Power on the system and test the smoke detection functionality.
