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 ...

MQ2 Smoke Sensor with Raspberry Pi. The smoke sensor we will use is the MQ2. This is a sensor that is not only sensitive to smoke, but also to flammable gas. The MQ2 smoke sensor reports smoke by the voltage level that it outputs. The more smoke there is, the greater the voltage that it outputs. Conversely, the less smoke that it is exposed ...

03/08/2014· I wanted to get acquainted with the MQ2 AirQuality Sensor so I took a look at the sketch from github. One thing I noticed was that there is some sleeptime defined, is this just to make the sensor report the value every 30 seconds? I guess it is not for saving power so you can run it on batteries because my understanding is that it needs to be hot in order to function correctly and that will ...
