Abstract
A gas sensing device includes a photoacoustic spectrometry device, including a radiator for emitting light, a gas detection chamber for exposing a mixture of gases to the light, a microphone for detecting sound in the detection chamber, which is caused by exposing the mixture of gases to the light, and wherein the photoacoustic spectrometry device generates signal samples corresponding to a concentration of the gas in the mixture of gases based on the sound detected by the microphone, and a computing device for receiving the signal samples. The computing device includes a feature extraction block including a trained model algorithm block.
