MQ series sensors - Sensors - Arduino Forum

2021-05-06· The MQ sensors are wired up to provide an analog input, which tells you (after calibration) the concentration of gas it is detecting. But it has no idea which gases contributed to that reading. Worse, the sensor may be intended to detect a particular gas or gases, but it may also be influenced by others in addition to those it is designed for.

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 ...
