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

All MQ-X sensors return analogue signals, which we can not easily read at the Raspberry Pi. One possibility would be to use an Arduino, but we can also use an analog-to-digital converter (ADC), which can be read out via the I2C bus. In addition, we also need a logic level converter. Analog-Digital Converter (8 Ports): US * / UK *.
