An Arduino Sketch for MQ2 Smoke Sensor to detect Cigarette Smoke using ATmega328P boards

## Pre-Requisities

- Arduino IDE

- Arduino UNO

- MQ2 Smoke Sensor

- Wires

- Soldering Kit

## Circuit Diagram

## Theory

We can measure PPM values using MQ2 sensor and a cigarette emits Carbon Monoxide(CO) as the main output gas so we're calibrating the MQ2 sensor to detect Carbon Monoxide levels and detect cigarettes.
