In our living environment, there are a lot of particulate matter floating in the air every moment. They are called total suspended particulate matter (TSP) in the air. TSP is the main component of air pollutants. In TSP, particulate matter with diameter less than 10 micron is usually called PM10, which is also called inhalable particulate matter or drifting dust. Inhalable particulate matter (PM10) is harmful to human respiratory tract and has a great impact on human health and atmospheric visibility. PM10 mainly comes from dust raised by wind or pollen emitted by plants.
PM2.5 refers to particles less than 2.5 microns in diameter in TSP, also known as particulate matter that can enter the lung. It mainly comes from the combustion of fossil fuels, such as motor vehicle exhaust, coal combustion, volatile organic compounds and so on. Compared with PM10, PM2.5 is much more harmful. Because of its long residence time and long transportation distance in the atmosphere, it has a greater impact on human health and atmospheric environmental quality. PM2.5 can directly penetrate human organs and enter the lungs, causing diseases including asthma, bronchitis and cardiovascular diseases because of its small diameter.
PM2.5 particulate pollution
1. Wear PM2.5 respirator: PM2.5 respirator in addition to dust, pm2.5, respirator fabrics can kill even antibiotics can not kill the "superbacteria" of the Kang fiber. The use of masks is undoubtedly an effective solution to the problem of dust and disease prevention. Especially on the way to and from work, in the subway station and in the crowded places.
2. Minimize smoking or even non-smoking: There are a lot of PM2.5 in the smoke, which will have direct and indirect harm to the human body. If you can't stop people smoking around you, you should try to stay away from the smoke.
3. Do not do morning exercises in foggy days: PM2.5 is one of the main causes of foggy weather, so it is not appropriate to go out for morning exercises when the fog is found in the morning.
Currently, PM2.5 sensors developed and produced by LUFTMY include infrared PM2.5 sensor and laser dust sensor.For example, the popular HPD05 infrared PM2.5 sensor can maintain normal operation under high concentration in harsh environment.LD series laser dust sensor represented by LD09 is well received.S7 dust sensor is specially developed for the dust cleanliness data of smart home sweeper and vacuum cleaner.
High precision dust sensor infrared dust sensor GDS06 uses the principle of optical scattering to measure the dust concentration within the detection range through the conversion of optical path and circuit. GDS06 has the characteristics of small size, high precision, low power consumption, short response time and stable operation under high dust concentration. The infrared dust sensor can be used in air purifier, air conditioning with purification function, PM2.5 detector, etc.
LD09 laser dust sensor is a high precision particle concentration sensor based on laser Michaelis MIE scattering theory. It can continuously collect and calculate the particle concentration distribution, and output in the form of universal digital interface. LD09 has the characteristics of small size, high precision, strong anti-interference ability, low power consumption, long life and short response time of zero error alarm rate. LUFTMY laser dust particle sensor LD09 can be embedded in various instruments or environmental improvement equipment related to the concentration of suspended particulate matter in the air to provide timely and accurate concentration data.
The dust particle sensor S7-L Smart Dust product uses the principle of optical radiation. The cleanliness particle sensor S7-L can accurately detect the number and concentration of particles in the ventilation duct of the equipment such as the handle of the vacuum cleaner or the extension rod pipe, the sweeping robot, the lampblack extractor, the particle detection instrument and so on. Application Benefits of S7-L Smart Dust in Vacuum Cleaner and Sweeping Robot Products: Cleaning effect of equipment and cleanliness of ground, carpet, bed sheet, etc. are presented intuitively to users through output data of sensor and color display of LED; Intelligent control of equipment based on sensor data The speed of the motor can achieve quiet energy-saving and power-saving, and prolong the life of the motor.
