Configure and read out the Raspberry Pi gas sensor (MQ-X)

Configuration of the Raspberry Pi Gas Sensor – Preparation. The concentration of a gas is given in PPM (parts per million). One difficulty of the MQ-2 is that a single analog value is given with which the gas content in the air has to be calculated for the various supported gases. However, the sensor must be configured for this purpose. Since this manual is also applicable to another ...
