Abstract
The present disclosure discloses an infrared sensor, an infrared gas detector and an air quality detection device. The infrared sensor includes electrodes, a substrate, an isolation layer and a graphene film. The graphene film has a periodical nanostructure. The infrared sensor enhances the absorption of infrared light, and is capable of only absorbing specific infrared wavelengths, thus improving the selective performance of the infrared gas detector.
