Air Quality Monitor

Air pollution is becoming more and more serious. The value of PM2.5 (referring to particulate matter with aerodynamic equivalent diameter less than or equal to 2.5 microns in ambient air) is a parameter index.


Indoor Air Quality Monitoring

The World Health Organization's "Indoor Air Pollution and Health" pointed out that the current level of indoor air pollution is 5-10 times higher than outdoor pollution, and 4% of global diseases are related to indoor air quality, and about 2 million people die prematurely each year from diseases caused by indoor air pollution.


Air Purifier

Winsen is a world-renowned gas sensor manufacturer and supplier. A variety of sensors are intelligently combined and developed to form the overall concept of the module. The extremely flexible assembly combination can meet the sensitivity, corresponding speed, stability, power consumption and size requirements of all air purifiers on the market.


Vehicle Air Quality

Vehicle exhaust contains hundreds of different compounds, including suspended solids, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides. Among them, hydrocarbons (HC) in automobile exhaust are the result of direct emission of unburned or insufficiently burned gasoline in the form of gas. Under the action of ultraviolet light,



Winsen Technology has provided accurate gas detection solutions for more than 1,000 fresh air enterprises, which has also established the influence of Winsen sensors in the air purification market. In the future, Winsen will launch more intelligent and miniaturized all-in-one integrated modules to meet the various needs of different customers in the ventilation system market.
