摘要：
There is provided a gas sensing device for sensing a certain gas that is associated with a certain spectral band, the gas sensing device may include a passive gas sensor that is configured to generate passive gas sensor detection signals that are responsive to the certain spectral band; a passive dummy sensor that is configured to generate passive dummy sensor detection signals that are indifferent to the certain spectral band; and at least one circuit that is configured to detect a presence or absence of the certain gas within a certain volume that is located within the fields of view of the passive gas sensor and the passive dummy sensor based on a comparison between the passive gas sensor detection signals and the passive dummy sensor detection signals.
