Abstract: A gas sensing system includes a driving circuit chip, and a gas sensor, a temperature sensor, and a humidity sensor, which are located on the driving circuit chip. The gas sensing system compensates a gas sensing result based on at least one of a temperature sensing result and a humidity sensing result and generates a gas sensing signal. The gas sensor includes a first resonator and a first sensing film being configured to sense a first gas and located on the first resonator to be exposed to the outside. The temperature sensor includes a second resonator and an encapsulation layer located above the second resonator not to expose the second resonator to the outside, and the humidity sensor includes a third resonator.
