Abstract

The invention relates to an air quality monitoring sensor based on a nanofiber membrane. The sensor comprises at least one silver-containing nanofiber membrane (110), a performance monitoring module (120) and a data processing module (130), wherein the performance monitoring module (120) is connected with the silver-containing nanofiber membrane (110) and sends electrical performance parameters ofthe silver-containing nanofiber membrane (110) to the data processing module (130) in a wired and / or wireless mode so as to form at least one change curve of electrical performance parameters relatedto working state parameters of the silver-containing nanofiber membrane (110), in which the data processing module (130) assesses the air quality on the basis of the operating state parameter of thecorresponding silver-containing nanofiber membrane (110) determined from the electrical performance parameter change curve when a voltage is applied to the silver-containing nanofiber membrane (110).By monitoring the silver loss degree of the silver nanofiber membrane, the air quality can be monitored while air sterilization is achieved.

Description

technical field [0001] The invention relates to the field of air quality monitoring, in particular to an air quality sensor of a nanofiber membrane and an air quality monitoring system. Background technique [0002] Nanofibrous materials have the advantage of high-efficiency filtration. In the current situation where air pollution has caused great harm to human health, nanofiber materials have been applied to the fields of dust emission filtration, automobile exhaust emission filtration, and smog masks. [0003] The contagious outbreak of the new coronavirus (COVID-19) in late 2019 pushed the importance of hygiene and environmental protection to an unprecedented height. How to protect the public from the perspective of health and environment has become an important issue that the whole society pays close attention to. The transmission route of the new coronavirus includes aerosol transmission. With poor air circulation, air-conditioning ventilation systems in buildings fu...
