How to Build a MQ2 Smoke Sensor Circuit with a Raspberry Pi

+

The gas sensor needs about 5 volts of power in order to operate. This is done by connecting 5 volts to Vcc and GND. The Output pin gives out the voltage reading, which is proportional to the amount of smoke that the sensor is exposed to. Again, a high voltage output means the sensor is exposed to a lot of smoke. A low or 0 voltage output means the sensor is exposed to either little or no smoke ...

20180611· No mention of calibrating the MQ2 sensor/breakout PCB, because not all MQ2 sensors are the same. The analogue output level can vary enormously in clean air, and setting a value of 500 for the alarm level is pointless if your MQ2 analogue output is already at 500 in clean air. Also, no mention of leaving the MQ2 powered up to stabilise (see MQ2 data sheet). According to the MQ2 data sheet, it ...
