MQ 2 Gas Sensor - IoCT

sensor is at working temperature and the platinum wires and SnO 2 form the sensing system. When the gas interacts with the sensor, the heat from the system ionizes the gas. This ionization allows SnO 2 to absorb the gas. This adsorption causes a change in the resistance on the sensor.
