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.

Arduino lesson – MQ-2 Smoke Sensor –

2018-11-16· Arduino MQ-2 Smoke Alarm. The circuit we will build is shown below. So to power the smoke sensor, we connect pin 2 of the smoke sensor to the 5V terminal of the arduino and terminal 3 to the GND terminal of the arduino. This gives the smoke sensor the 5 volts it needs to be powered. The output of the sensor goes into analog pin A0 of the arduino.
