MQ2 Gas Sensor Tutorial for Arduino, ESP8266 and ESP32

· The analog sensor value increases due to the increase of gas concentration. The potentiometer must be calibrated in a way that if there is no relevant gas concentration, the input voltage of the comparator (3) has to be higher than the output voltage of the MQ2 sensor that equals the reference voltage of the comparator (2). In this case, the output of the comparator is equal to VCC and ...
