With the continuous improvement of living standards, people's demand for automobiles is also rising. With the spread of air pollution and automobile pollution, it is so difficult for people to enjoy fresh air in the process of driving. The environment inside the car is not good, there is a bad smell, and the air outside the window is worse than that inside the car.

1. what pollutants are in the car

(1)musty smell: this may be the car air conditioning system for a long time did not clean and caused by the evaporator and wind tunnel in the generation of bacteria, bacteria mildewy odor;

(2)gasoline smell: gasoline purification carbon canister rubber aging; Leakage of gasoline pipe interface, need to be tightened/repaired; After disassembling the gasoline pump, the sealing performance becomes worse. The car fuel is too full, may also cause the car gasoline smell;

(3)after the purchase of a new car, open the door will smell a relatively strong smell of plastic and rubber, sitting in the car for a long time even more have made passengers vomiting or fainting phenomenon. For the first few months of production of plastic parts have a faint taste, and by the stability of chemical properties;

In addition, the plastic framework and leather are held together by glue. The glue itself contains a series of pungent smells, including benzene compounds and glass uric acid. After exposure to the sun, these items will emit formaldehyde, benzene, TVOC, xylene and other harmful substances, causing an impact on human health.

2.How to detect and deal with the pollution inside the car

For these invisible gases, we only through the air quality sensor to detect the existence of, through the LED digital display, it is intuitive to know what is in the air pollutants and how much is his concentration, if the air quality sensor module is installed inside the air purifier, such not only achieve the effect of monitoring, can also be detected when the car pollution reaches a certain concentration, automatically open car air purifier, so we can keep our air is fresh at any time.

Laser dust sensor module LD11 is a high-precision particle concentration sensor based on MIE scattering theory of laser, which can continuously collect and calculate the number of suspended particles of different particle sizes in the air per unit volume, namely the concentration distribution of particles, and then convert it into mass concentration, and output it in the form of universal digital interface. Luftmy air quality sensor can be embedded with various instruments or environmental improvement devices related to the concentration of suspended particulate matter in the air, providing timely and accurate concentration data.
