The connection between Arduino and MQ2 Sensor is very simple. VCC: Connect the VCC pin of the MQ-2 sensor module to the 5V out pin on the Arduino. GND: Connect the GND pin to the ground pin on the ...

It uses a thermal resistance to measure the gas concentration. To operate the MQ2 sensor with Arduino, connect the VCC pin of the sensor to the 5V pin of the Arduino, the GND pin of the sensor to the ...

Now that we have complete understanding of how the MQ-2 gas sensor works we can connect all the required wires to Arduino uno. This section of the article will be divided into two parts, one shows ...
