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) ...

MQ-2 Gas and Smoke Sensor Module – Parts. 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 ...

It really is a hands-on way to learn electronics and programming while building a useful gadget. Get your Arduino board and gas sensor to start creating your smoke detector today. Write a code for ...

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 ...

This Arduino sketch is designed to monitor environmental conditions using a DHT sensor (temperature and humidity), an MQ2 smoke sensor, and an LCD display. Additionally, it integrates a GSM module ...

Arduino Smoke Detector Code. Code Overview. Before diving on to the actual code. Let’s understand the core logic behind this program. Basically, this program enables the Arduino UNO R4 to connect to ...

On the left-hand side, we have placed the Arduino with the GP2Y1014AU0F sensor connected to the ADC pin of the Arduino and on the right-hand side we have the serial monitor window, and as you can see, ...
