Humans can detect many scents, but can have difficulties when it comes to differentiating gases. That’s why we use sensors like MQ6. It detects LPG and butane in the air. When heated to the optimum working temperature, it detects changes in air concentrations very quickly between 200 and 10000 ppm.
The DO pin stands for digital out. AO stands for analog out. The digital output is obtained by setting a threshold value using the potentiometer. The analog output will depend on the intensity of the gas around the sensor.
