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.

MiCS5524 Gas Sensor - IoCT

Solder the pins to the sensor before connecting to the raspberry pi. In order to connect the MiCS5524 sensor to the Raspberry Pi, two other sensors are needed. A level converter is needed to take the 5V output signal to a signal and an A/D converter to be able to read the signal in digital form. It is necessary to step the voltage down because a raspberry pi can only read signals at ...
