Haze weather is becoming more and more common in recent years, and air pollution always affects our health. Air quality problems have aroused great concern of the whole society. With the improvement of people's living standard and the improvement of people's health consciousness, more and more attention has been paid to the related air quality monitoring and air purification products. The most noticeable goal is the intelligent extreme of air monitoring such as haze detector, purifying products such as air purifier with PM2.5 sensor, fresh air system and so on. Experience, so that fresh air is no longer a luxury.
Air purifier products are different from air conditioning. As far as ordinary consumers are concerned, it is difficult to establish a very intuitive feeling about the effectiveness of air purifier products purchased by them. Relevant monitoring data are needed to give a fair evaluation. Therefore, smoke and dust sensors and PM2.5 sensors have gradually attracted industry attention. The only way to evaluate indoor air quality is sensors, which can sense the concentration of harmful components in the air. They are more important bridges between air purifier products and users.
In the domestic and foreign high-end air purifier market, the application of dust identification sensor and PM2.5 sensor has been very extensive, and it is one of the necessary sensors for intelligent air purifier. With the rapid growth of domestic air purifier market, dust sensor technology is also developing rapidly, especially laser dust sensor has been developed rapidly.
LD13 laser dust sensor module 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, and then convert it into mass concentration, and output it in the form of universal digital interface. This laser PM2.5 dust sensor can be embedded with various haze detector, fresh air system and other instruments or environmental improvement equipment related to the concentration of suspended particulates in the air, providing timely and accurate concentration data.
