Air quality sensor ENS145 for vehicle-mounted air purifier

With the continuous improvement of living standards, many people have bought cars. However, with the continuous deterioration of air quality in some cities in recent years, especially in summer, everyone likes to turn on the air conditioner, and the air in the car is not circulated, which is easy to breed bacteria, mold and other microorganisms, which will pose a threat to human health.

According to Gongcai.com, in-car pollution mainly refers to the problem of poor air quality caused by lack of ventilation and car body decoration. Among them, the pollution sources mainly come from the car body itself, decorative materials, etc. Among them, formaldehyde, xylene, benzene and other toxic pollution are the most serious. They are all carcinogens and also belong to VOCs (volatile organic compounds). In addition, the air in the car "inhaled" by the air conditioner also contains a lot of exhaust gas.

There are many other sources of odor in cars: for example, in order to meet consumers' demand for beautiful and comfortable interiors and energy-saving and lightweight cars, automobile companies use a large number of non-metallic materials in the production process of interior decoration, such as polypropylene, polyurethane, PVC, leather, TPV, rubber, ABS, fabrics, etc. Due to the material characteristics of these interior decorations and the various additives and additives added during the production process, consumers will continuously release some odorous volatile substances during the later use of the car, causing odor inside the car.

In addition, the leather in the car will have a smell after being used for a long time, which will also cause harm to our health over time. Therefore, in order to solve this problem, the car air purifier came into being. The car air purifier can make the air in the car fresher and can also reduce our discomfort when driving and riding.

The car air purifier has multiple purification functions. It can actively purify every part of the car, effectively kill harmful germs and bacteria in the air, and remove dust, smoke and odor. It is also equipped with an air quality sensor , which can be used to detect the concentration of VOC gas and odor in the car. If the concentration exceeds the standard, the purifier can be turned on in time to purify the air environment in the car.

Gongcai.com represents the AMS MEMS technology ultra-small metal oxide semiconductor principle air quality sensor - ENS145, which is used to widely detect reducing gases and oxidizing gases related to bad air, such as VOC, CO and nitrogen oxides (NOx). The ENS145 air quality sensor element is a MEMS technology sensor with long life and long-term stability.
