Abstract

The invention discloses an electronic nose for detecting indoor air quality. The electronic nose mainly comprises a nose frame, a shell, a suction fan, HEPA (High Efficiency Particulate Air) filter paper, a nasal cavity, a gas sensor array and a processing circuit integration module thereof, a DSP (digital signal processor), a human-computer interaction interface, a harmful gas absorption and purification device and the like. The electronic nose is characterized in that indoor air to be detected is sucked into the nasal cavity by the suction fan through the HEPA filter paper to perform a full reaction with the gas sensor array; the measurement and identification of harmful gases in the air are completed inside the nasal cavity; then the harmful gas absorption and purification device is used for absorbing and purifying harmful gases with high concentration. The electronic nose has the characteristics of small size, anti-interference, quickness, accuracy, secondary pollution prevention and the like, and is suitable for detecting the harmful gases in the indoor air.

Description

technical field

[0001] The invention relates to an electronic nose for indoor air quality in the field of environmental monitoring, in particular to an electronic nose for indoor harmful gas detection, identification and judgment, and alarm processing. It belongs to the field of gas monitoring and pattern recognition, and is suitable for air quality detection and purification control in relatively closed environments such as ordinary homes, studios, computer rooms, and cars. Background technique

[0002] With the continuous development of industrial enterprises, various pollutants are entrained in the air to varying degrees. Usually in the open and naturally ventilated outdoors, the pollutants in the air have relatively little impact on people's health. However, with the improvement of people's living conditions, interior decoration is universal, and decoration materials such as stone, chemical wallpaper, carpets, paints, coatings, etc., are not environmentally friendly enou...
