The role of air quality sensors in environmental monitoring

Update: 2019-12-18 15:43 Source: LUFTMY Reading: ↻ News

Environmental pollution is an urgent problem in our country. Because of the complexity of the source, the difficulty of monitoring, the monitoring means and density are far from the current needs, there are great difficulties and challenges for the study of the impact of air pollution on human health.Air quality sensor uses a variety of comprehensive technologies, such as microelectronics, sensor technology, signal processing technology, etc., to minimize the cost of hardware, minimize the volume, simplify the use of software products, operate quickly, and use a wide range, which will play an important role in environmental encryption monitoring.

For the application of air quality sensor in environmental monitoring in recent years, more and more enterprises produce air quality sensor in our country. These enterprises combine the requirements of national control and monitoring, develop and produce most parts of sensor, introduce key components, reduce the cost of air quality sensor development, and adapt to the purchasing power of users. Because the research of air quality monitoring instrument technology modernization in China started later than that in foreign countries, there is still a certain gap between China and foreign countries.

At present, most of the air quality sensors in our country are imported from abroad. However, due to the difference of the actual environment in various countries, there is a large gap in the demand of system structure, data collection, monitoring management and operation and maintenance of the imported equipment in our country. Therefore, the direct reference of foreign equipment is not suitable for the demand of air quality monitoring in our country.

The air quality sensor is mainly used in various air purification devices and small household appliances. It has high sensitivity to various pollution sources such as alcohol, cigarette, ammonia, sulfide, etc. the product has fast response time, stable operation and low price. You can know the air condition in the room through the air quality sensor, so as to clean and improve your environment to a certain extent.

Built-in air quality sensor for air detector

PM2.5 detector
PM2.5 detector

The air quality monitoring module PM2.5 detector is a special instrument for measuring the value of PM2.5 in the air. It is applicable to the measurement of public place environment, atmospheric environment, indoor air and vehicle air, as well as the evaluation and analysis of purification efficiency of air purifier. The portable dust concentration sensor air quality monitoring module uses the laser PM2.5 sensor based on Mie spherical particle scattering principle, and uses POS particle swarm optimization algorithm to retrieve the mass concentration of particles, which makes the data reading fast and accurate.

LD15 Laser dust sensor

LUFTMY air quality sensor model LD15 is a high-precision particle concentration sensor based on laser Mie scattering theory. It can continuously collect and calculate the number of suspended particles with different particle sizes in the air per unit volume, i.e. particle concentration distribution, and then convert it into mass concentration, and output it in the form of general digital interface.The air quality sensor model LD15 has the characteristics of small volume, high precision, strong anti-interference ability, low power consumption, long service life, short response time of zero error alarm rate, etc. the sensor monitoring air quality can be embedded with various instruments related to the concentration of suspended particles in the air, such as PM2.5 detector or environmental improvement equipment, providing timely and accurate concentration data.
