An Arduino Sketch for MQ2 Smoke Sensor to detect Cigarette Smoke using ATmega328P boards
- Arduino IDE
- Arduino UNO
- MQ2 Smoke Sensor
- Wires
- Soldering Kit
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.
