Sep 09, 2019So the fuil circuit as follows : Raspberry PI - Logic Level Shifter - ADC - MQ2. This schematic should be self explanatory, but just to make few things clear, the red wire is 5 V which are provided by our RPi, but you can use an external power supply if you wish. Also notice the that we have to provide 3.3V to Logic Level Shifter by connecting orange wire to LV and then 5V to HV.
