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 …
