摘要
Embodiments relate generally to systems and methods for detecting gas using a wide band light source, and at least two narrow band light sensors, wherein each sensor may be operable to detect light at a different range of wavelengths. Additionally, the gas detector device may comprise a color changing indicator operable to react with gas in the air to change color, wherein different gases may react to create different colors, and wherein the sensors detect light reflected by the color changing indicator from the wide band light source. The gas detector device may comprise a processor in communication with the at least two light sensors operable to receive detected reflected wavelength information from the light sensors, and determine the type of gas that reacted with the color changing indicator based on the color detected by the sensors, wherein each color may be associated with a different type of gas.
