  • Patent number: 12259319
    Abstract: A gas sensing device for detecting a to-be-detected substance in a respiratory gas exhaled by a user includes a housing permitting entrance of the respiratory gas, and a sensing module disposed in the housing. The sensing module includes a light chamber permitting the respiratory gas to pass therethrough, a light source unit emitting light into the light chamber, first and second light sensing units outputting respectively first and second detected signals indicating first and second detected intensities respectively of first and second portions of the light whose wavelengths fall within first and second wavelength ranges, respectively, and a processing unit electrically connected to the first and second light sensing units and determining, based on the first and second detected signals, that the to-be-detected substance exists in the respiratory gas when a difference occurs in each of the first and second detected intensities over time.
