PM2.5 sensor applications : new air system

Update: 2019-08-25 16:22 Source: LUFTMY Reading: ↻ News

What is a new air system?

Fresh air system is a new type of indoor air purification equipment. Through forced air supply and exhaust ventilation, the window is not opened, allowing indoor and outdoor air to replace each other. The fresh air system is a set of open air circulation system, 24 hours for indoor Everfount provide fresh oxygen enriched air, popular in the early last century in Europe and the United States in 70s housing has, in recent years in the domestic many family residential and commercial housing is also widely used in villas.

What are the functions of the new air system:

1 ,Ventilation and effective aeration.

2, Filter PM2.5, powerful anti haze.

3, Remove indoor harmful gases, care for health.

4, Control the indoor temperature, prevent dry and tide removing.

The role of PM2.5 sensors in the new air system:

The main function of the new air system is to intelligently filter PM2.5, haze, and purify air in the air. The sensor module monitors and detects the concentration of dust in the air by using the principle of optical scattering. The PM2.5 sensor with an infrared emitting diode and a high sensitive photoelectric sensor, infrared light emitting diode emits light will generate reflected light in the face of dust, the photoelectric sensor by detecting the reflected light intensity to reflect the concentration of dust in the air. When the dust concentration in the air is too high, the fresh air system will start the PM2.5 filter function to achieve the effect of purifying air.

LD12 Laser PM2.5 Dust Sensor Model - LUFTMY

LD12 Laser PM2.5 Dust Sensor Model

PM2.5 laser dust sensor module LD12 is a high-precision particle sensor based on the theory of laser MIE scattering. It can continuously collect and calculate the number of suspended particles with different particle sizes in air per unit volume, that is the concentration distribution of particles, and then convert to mass concentration. And output in the form of universal digital interface.
