Abstract
A gas sensing method and a gas sensing system are provided. The gas sensing method includes using a gas sensing device to sense a target gas, the gas sensing device having a self-heating region capable of producing a change in resistance in response to the target gas being sensed by the gas sensing device, and controlling a change in supply of current or voltage to the gas sensing device according to the change in resistance, so that the gas sensing device is substantially maintained operating at a predetermined temperature for sensing the target gas.
