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) ...

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 ...

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 ...
