Interfacing MQ-4 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 MQ-4 Gas sensor has a built-in variable resistor that ...
