For the code, please visit:

Circuit connections:
Arduino to Oled:-
gnd = gnd
3v3 = vcc
A5= scl
A4 = sda
Arduino to gas sensor:-
gnd = gnd
vcc = vin
A0= aout
Components used :-
1.mq3 alcohol gas sensor(you can use any sensor, no coding change is needed)
2. Arduino Nano(you can also use uno and mega)
3. Arduino OLED I2C display 0.96in 128X64 (you can use other display sizes too but changes in coding needed. You should use only oled display, graphical display needs bigger change in coding, will upload soon)
Wait and watch our next video pollution indicator V3.0 with IoT and graphical display and live tutorials.
