Application of various sensor technologies in vehicle air purification system

With the increasing market demand for family cars , many cars enter the market directly after leaving the production line. There is no release period for the harmful gases and odors of various accessories and materials. The plastic parts, carpets, and roof felt installed in the car If you do not comply with strict environmental protection requirements, it will directly cause air pollution in the car.
In -car air purification market has broad prospects.
With the intensification of air pollution and smog in various places, bacteria and viruses are rampant, and air purification has become a hot spot. As the space where people come into daily contact , car air purification has also become the focus of attention. In response to this kind of consumer demand, many domestic auto companies currently regard in-car air purification as a prominent selling point of their products . Relevant experts said that the air purification technology market has broad prospects, and the size of the air purification market in vehicles alone is expected to reach one trillion yuan.
Air pollution in the car is seriously harmful.
Sources of pollutants
1. During the production of the vehicle, a large number of plastic products and adhesives are used for interior parts. These are the main culprits of environmental pollution in the car. The solvent used in the adhesive is the interior of the car. main source of pollution.
2. After the engine runs for a long time, not only the heat generated by it will increase the volatilization of pollutants in the car, but also the amines, nicotine and other substances it produces will also cause harm to the body of the occupants.
3. Putting some inferior plush toys, cushions and other decorations in the car will increase the release source of "formaldehyde" in the car. Others like to spray perfume in the car. Many perfumes are chemical compounds, which also contain harmful substances, which will only increase the pollution.
4. Automobile exhaust gas. There are about 150 to 200 kinds of exhaust gases after chemical analysis, among which carbon monoxide, hydrocarbons, nitrogen oxides, carbon and other gases and particulate matter are more harmful to human body. harm

Intelligent purification
When the monitored data exceeds the standard, the system will first command the air conditioning system to use the external circulation to inhale fresh air, and filter pollen, odor and some allergens through the filter element. There is a purifier in the car, which can be linked with the purifier to turn on the purification function.
Intelligent
temperature and humidity control Install the temperature and humidity sensor HTW-211 near the cockpit of the car, and adjust the dehumidification mode of the air conditioner by detecting the humidity in the cockpit to avoid excessive humidity in the car or dryness due to excessive dehumidification. There is a humidifier, and it can also be linked with the humidifier to turn on the humidification function. South KoreaSamyoungThe HTW-211 temperature and humidity sensor produced has cooperated with Ford Motor. So far, the field defect rate has reached 0ppm. Ford Motor has recognized the quality and durability of South Korea's Samying HumiChip temperature and humidity sensor, ensuring AEC-Q100 Grade 1 vehicles reliability . _ Passed the AEC-Q100 vehicle regulation certification.

There are generally 1-2 temperature and humidity sensors located in the ventilation ducts in the car compartment, which measure the temperature in the car, transmit the signal to the electronic control unit ofthe automatic air conditioner
