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.

Oct 7, 2020 · In this project, we will learn how to create a smoke detector using Arduino. This will help us detect the intensity of gases.

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.

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

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.

Apr 1, 2022 · In most Arduino projects, the MQ-2 sensor is used to detect hazardous or flammable gas or smoke and hence this sensor is popular among beginners. Also these are low cost, easy to use sensors featuring a wide sensing range that can be trimmed down to adjust the sensitivity. The parts markings of the MQ-2 Gas Sensor is given below-

Oct 21, 2022 · You simply need an Arduino, an MQ-2 sensor, and a few immediately available basic electronic components. To create a smoke detector using an MQ-2 gas sensor, follow the instructions. Schematic. Make connections according to the circuit diagram given below. Wiring / …

A smoke detector alarm automatically detects the smoke and gives a warning to be aware of it. Most accidents occur due to the absence of humans in the right place at the right time. As soon as smoke is detected the circuit is activated and the buzzer is turned on.

In this DIY session, we are going to build a Smoke Detector Circuit which not only sense the smoke in the air but also reads and displays the level of Smoke in the Air in PPM (parts per million).

This Simple Smoke Detector Alarm Circuit uses the MQ02 sensor, having three pairs called A, B, and HB pins are for the supply voltage, while A and B are interchangeable. To use this MQ02 sensor directly connect three pins at one side to the bias voltage. For example, we have connected B1, B2, and HB to that bias supply voltage. .
