Experiment 3 How to Use MQ-2 Gas Sensor - sunfounder

In this experiment, we will learn how to use the MQ-2 gas sensor. With the value displaying on the serial monitor, we can intuitively know the concentration value of surrounding combustible gas. The higher the concentration of combustible gas is, the greater the value is; the lower the concentration is, the smaller the value is. Components:

How to Build a MQ-2 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 ...

Interfacing MQ-2 Gas Sensor with evive - STEMpedia

MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kind of gases combination. They can be calibrated, but, in order to do that, a known concentration of measured gas or gases is needed. In our case, we will test it, as it comes from the producer without any additional calibration. The MQ2 Gas sensor has a built-in variable resistor that …
