Carbon dioxide (CO2) is a colorless and odorless gas at room temperature. It is widely found in industry, agriculture, animal husbandry, residential environments and public places. However, high level CO2 can cause human body poisoning.Therefore, carbon dioxide monitoring is used in production processes that are prone to occupational exposure to various hazards that produce carbon dioxide, such as beer and beverage brewing, CO2 emission control in industrial sites, CO2 control in the transportation of fruits and vegetables, and cold storage environments.

Keeping low CO2 level is important for human health, which not only means that the current environment has sufficient fresh air, but also greatly reduce the risk of building syndrome. Winsen CO2 sensor meets RESET standard, which is widely used in control panels or thermostats for HVAC systems.

With the rapid development of the economy and the improvement of people's living standards, people have more and more attention to intelligent agriculture and livestock industry. Greenhouse planting has been quickly promoted and applied and it also manifests in smart granary, incubator, soil CO2 detection and other aspects.
