mq2 gas sensor raspberry pi code

MQ-2 Gas Sensor Module - Wiki

The codes above are used to acquire the signal of the gas sensor via the analog interface 0 and to output the signals into the computer via serial port. To observe the consequence, we can use serial port monitor. Due to the internal structure of the gas sensor, the measurement can only begin after one minute's preheating.
