People pay more and more attention to the air quality. Private cars have become the first choice for people to travel. This also causes the environmental protection of cars and the fresh air in cars to become the topic of discussion.In order to detect the concentration of harmful gases in gases, gas sensors such as air quality sensors are needed. By converting the measured concentration into corresponding digital standards, users can clearly know the air quality around them. These are particularly important in the field of automobile sensors. So what pollution are there in the car?

New cars often directly into the market after the production line, all kinds of accessories and materials of harmful gas and odor release period, installed in the car's plastic parts, carpets, roof felt, sofa, if not in accordance with strict environmental requirements, will directly cause air pollution in the car.
The condition of poor air quality caused by lack of ventilation and body decoration. Indoor air pollution sources mainly come from the car itself, decorative materials, etc., among which formaldehyde, xylene, benzene and other toxic substances pollution consequences are the most serious.
When the air quality is bad, the air in the car will be affected. In addition, road exhaust, PM2.5, industrial dust and bacteria are all sources of pollution, which can be detected through the detector equipped with dust sensor.
If the evaporator of car air conditioner does not clean and care for a long time, it will attach a lot of dirt inside, and the harmful substances such as amine, nicotinic acid and bacteria will diffuse in the narrow space inside the car, resulting in poor air quality inside the car and even hypoxia.
If a driver or passenger smokes, not only does it significantly increase levels of air pollutants such as volatile organic compounds, carbon monoxide and dust, but the odors it gives off can also linger for a long time.
Interior decoration is a lot of people's favorite, but these decoration materials contain toxic gas, mainly including benzene, formaldehyde, acetone, xylene and so on.
Such pollutants are invisible to the naked eye. When we smell them, the concentration is quite high. This can only be detected with the help of the automobile air quality sensor, so that the pollutants in the air can be well detected and displayed through the digital panel, and then purified with the on-board PM2.5 sensor loaded on the vehicle. The use of the device can not only detect the air quality at any time, but also handle the quality situation at any time.
