ESP8266 WiFi gas sensor (Arduino IDE)

2  · 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.
