MQ 2 Gas Sensor - IoCT

Figure 2: Schematic of MQ-2 Gas Sensor from Datasheet. 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 …
