Smoke Detector using Gas Sensor using arduino A Smoke Detector using a Gas Sensor for Arduino is a prime example of a project that assures beginners and hobbyists in learning how to develop a safety ...

I will attach all the schematics and the PCBs design for the project. I will start by doing the PCB design for the smoke sensor detector. Components: Arduino UNO; Power Supply; Smoke Sensor (MQ2) ...

Key Components: Gas Sensor: A sensitive gas sensor is employed to detect the presence of smoke particles in the air. The sensor provides analog or digital output based on the concentration of smoke ...

Insert the Arduino Nano and MQ-2 smoke sensor in the breadboard. Power up the sensor through Arduino and connect the A0 pin of the sensor to A5 of Arduino. Connect a buzzer and an LED in a parallel ...

This circuit mainly uses MQ6 Smoke/Gas sensor to detect the level of smoke. MQ6 gas sensor is also sensible to LPG, Alcohol, and Methane etc. Here we have used Buzzer as a Smoke alarm, which is driven ...

Do not try to build your own smoke alarm. ... their life to a $5 development board and some Arduino source code they copied ... , home automation, MQ2, NodeMCU, smoke detector, smoke sensor.

Arduino Flame Sensor Code. The code for interfacing the flame sensor is very simple and easy to understand. We just need to define the pin through which the sensor is connected with the Arduino. Once ...
