In recent years, due to environmental pollution, the incidence of respiratory diseases, influenza and respiratory infectious diseases in Chinese cities has remained high. The frequent diseases make people pay more and more attention to the air quality. Masks, air purifiers, fresh air systems and other products once triggered a rush to buy, and thus formed a considerable "air economy".

What is the fresh air system?

The fresh air system is a new type of indoor air purification equipment. Through forced air supply and exhaust, the indoor and outdoor air can be exchanged without windows. The fresh air system is a set of open air circulation system, which can provide fresh oxygen rich air for the room continuously 24 hours

What are the functions of the fresh air system

1. Ventilation and effective oxygen increase

2. Filter PM2.5 to resist haze.

3. Remove indoor harmful gas and take care of health.

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

Function of PM2.5 sensor in fresh air system:

One of the main functions of the fresh air system is to filter PM2.5 and haze in the air intelligently and purify the air. The sensor module uses the principle of optical scattering to monitor and detect the concentration of dust in the air. PM2.5 sensor has a built-in infrared light-emitting diode and a highly sensitive photoelectric receiving sensor. When the light emitted by the infrared light-emitting diode encounters dust, it will produce reflected light. The photoelectric sensor reflects the concentration of dust in the air by detecting the intensity of the reflected light. When the dust concentration 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 economic and social development, people's living standards continue to improve, environmental pollution is becoming more and more serious, causing widespread concern. As the main component of haze PM2.5 detection has also become the leading role of the environmental protection department air quality report.

The traditional PM2.5 environmental detector is expensive and inconvenient to use, so it is difficult to apply in the family. Many types in the market have the characteristics of small size, easy to carry, high cost performance, convenient and flexible use, etc. the built-in PM2.5 sensor and smart home PM2.5 environment monitor with good detection effect came into being, so as to realize the real-time detection of PM2.5, which is suitable for the detection characteristics of PM2.5 and temperature and humidity in the home environment.

LUFTMY, air particle sensor manufacturer——The infrared counter counting sensor GDS06 uses the principle of optical scattering to obtain the concentration of particles. The intensity of light is directly proportional to the intensity of the electrical signal converted by photoelectric. The relative attenuation rate can be obtained by measuring the electrical signal, and then the dust concentration in the field to be measured can be measured. Then the single chip microcomputer is used for PWM and UART communication. The infrared counter counting sensor gds06 has the characteristics of small volume, high precision, low power consumption, short response time, wide measurement range, convenient application, etc. the particle detection sensor can be used in air purifier, fresh air system, PM2.5 detector environment detector, etc.
