Hello everyone , the name of this mini project is "SMOKE DETECTION USING ARDUINO" which comes under IOT(Internet of Things). ... detection of cigarette smoke and noise within the study room routinely ...

DIY Smoke Detector using Arduino. Make your very own smoke sensor with an Arduino and MQ-2 sensor, in this project you can learn how to calibrate the MQ-2 sensor to specifically react to smoke, other ...

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 ...

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) ...

We built a Smoke Detector Circuit using Arduino and MQ2 gas sensor, ... All MQ sensors have the same pinouts so you can replace directly. Just make sure the Vcc, Gnd and Analog pins are connected ...

This study is carried out using an arduino-uno microcontroller and MQ-2 gas sensor to address the demand. MQ-2 was chosen because it has a low price and good durability. In this work, an Arduino-uno ...

While this gas leakage detector using Arduino uses the MQ-5 sensor, understanding the differences between gas sensors helps you choose the best option for your specific needs. The MQ-2 sensor detects ...
