PM2.5 sensor, also known as dust sensor, it can sense the environment within the scope of the dirt, dust, pollen, such as fine particulate matter, these tiny particles suspended in the air for a long time easy to cause air pollution, and some of the production environment such as housing construction, cement production will produce large amounts of dust, people live and work in this environment can cause great damage to the respiratory tract and lungs.
Hazard of dust
Dust is an important factor leading to occupational diseases, and dust control is the top priority of labor hygiene work.A set of effective dust detection technology is needed for scientific labor health monitoring.Dust is a kind of dispersed phase aerosol, usually produced in the workplace such as mining, casting, textile production process, dust material transportation and agriculture, forestry work.The larger the dust particle size is, the easier it is to settle. Generally, dust with particle size greater than 5 can settle quickly.The harm of dust to human body is not only related to the chemical composition of dust and the amount of dust deposited in the lungs, but also related to the size of dust particle size and its settling position in the respiratory system, especially the dust particle size settling in the alveoli.
In the production process of industrial and mining enterprises, a large number of dust will be produced. Dust not only harms human health and causes occupational diseases, but also accelerates mechanical wear and shorens the service life of precision instruments. It is explosive under certain conditions.Dust is generated in various production links in the production process of industrial and mining enterprises, such as drilling, blasting, driving cutting, top-coal caving, construction, cement production, open-pit stope mining and stripping, crushing, ore dressing and screening.Working in a high-concentration dust environment for a long time, production workers will inhale a large amount of fine dust, which will seriously harm human health and cause occupational diseases such as coal lung disease and coal silicosis.In order to protect the life and health of workers, it is necessary to detect and control productive dust.
Application of PM2.5 sensor in dust detection and treatment
In order to timely grasp the concentration of dust in the environment, PM2.5 sensors are widely used in dust detection and treatment.PM2.5 sensors are usually classified into infrared sensors and laser sensors, which are widely used in indoor environment and industrial production.LD13 laser dust sensor is recommended by LUFTMY. Precise measurement is achieved by combining the principle of laser MIE spherical scattering and the patent of LUFTMY space measurement. The shell shielding is combined with the software anti-interference algorithm, with stronger anti-interference performance.Wide range of applications, no need for air duct design, compatible with multi-protocol output;Multi-interface design, suitable for air purifier, fresh air system, etc.
