MQ 2 Gas Sensor - IoCT

2The MQ 2 sensor is a metal oxide semiconductor (MOS), also known as a chemiresistor. MOS sensors measure the change in resistance when gases are present. This type of sensor requires the gas to encounter the sensor for a chemical reaction to occur. This chemical reaction causes a change in resistance, which is then measured to detect the presence or concentration of the gas. However, the …

MQ-2 Smoke/LPG/CO Gas Sensor Module | Sandbox Electronics

Based on the chart provided in the MQ-2 datasheet, R S in clean air under given temperature and humidity is a constant,which is the “initial” resistance of the sensor named R O. R O of the resistor could be derived from R S. The main job of the calibration is to calculate the R O by sampling and averaging the readings when the module is placed in the clean air. Once the R O is derived, the concentration of …
