Due to environmental pollution, the incidence of respiratory diseases, influenza and respiratory infectious diseases has remained high in China's cities in recent years.More and more diseases make people pay more and more attention to air quality. Masks, air purifiers, fresh air system and other products once triggered a rush rush, and thus formed a considerable scale of "air economy".Thus, has been silent unknown new wind market ushered in a new climax.

What is a fresh air system

Fresh air system is a new type of indoor air purification equipment. It can replace indoor and outdoor air without opening Windows by means of forced air supply and exhaust.Fresh air system is a set of open air circulation system, which can provide fresh and oxygen-rich air for indoor continuously 24 hours. As early as the 1970s, it has been widely used in European and American residential areas. In recent years, it has also been widely used in many domestic family residences and villa commercial rooms.

What are the functions of the fresh air system:

1, ventilation, effective oxygen

2. Filter PM2.5 and effectively combat haze.

3. Remove indoor harmful gases and care for health.

4. Control the indoor temperature to prevent drying and moisture removal.

Application of PM2.5 sensor in fresh air system:

One of the most important functions of the fresh air system is to filter PM2.5 and haze in the air and purify the air. The sensor module USES the principle of optical scattering to monitor and detect the concentration of dust in the air.The PM2.5 sensor is equipped with an infrared led and a highly sensitive photoelectric sensor. The infrared led emits light that reflects light when it encounters dust. The photoelectric sensor detects the intensity of the reflected light to reflect the concentration of dust in the air.When the concentration of dust in the air is too high, the fresh air system will automatically start the PM2.5 filtering function to achieve the air purification effect.

With the development of economy and society, people's living standard has been constantly improved, and environmental pollution has become more and more serious, which has aroused people's wide concern, especially the haze problem in north China.The detection of PM2.5, the main component of haze, has also become the protagonist of the air quality report of the environmental protection department. Currently, the detection technology of PM2.5 in China is quite mature, and the air quality report is also updated in real time.

Traditional PM2.5 environmental detector is expensive, inconvenient to use, difficult to be used in the family.Many types on the market are characterized by small size, easy to carry, high cost performance, convenient and flexible use, etc., with built-in PM2.5 sensor and good detection effect, smart home PM2.5 environmental monitoring device emerges at the right moment, so as to realize real-time detection of PM2.5, which is suitable for the detection of PM2.5 and temperature and humidity in the home environment.Among these smart home monitors, LUFTMY recommends the following PM2.5 sensors:
