Smoke Detector System Using MQ2 Gas Sensor and Arduino

Dec 22, 2020· The MQ2 is one type of gas sensor, which can sense Smoke as well as LPG, Alcohol, and Methane. Arduino board is the main brain of this system that controls the whole system. The MQ2 sensor continuously measures Smoke level in the air and sends data to the Arduino board. Then Arduino prints the Smoke level value on the OLED display in the PPM unit.

ESP8266 WiFi gas sensor (Arduino IDE) -

Use gas sensor digital output and connect it to ESP8266 GPIO2 pin. Because ESP8266 operates on and gas sensor operates on 5V we will add additional NPN transistor, two resistors and capacitor for voltage level sifter. Don't forget to add capacitor - it helps to set GPIO2 pin high during power on, to boot ESP8266 in correct state.
