With the rapid development of modern industry and transportation, the emission of smoke, dust and automobile exhaust has exceeded the self-purification limit of the atmosphere, followed by a very serious problem - air pollution. The pollutants that have great influence on air pollution are sulfur oxides, nitrogen oxides, hydrocarbons, carbon oxides, dust and so on.

The air pollution
The air pollution

The harm of several air pollutants to human body:

Dust: Damage to eyes, reduced visual range, chronic tracheitis, infantile asthma and pneumoconiosis, increased mortality, reduced visibility, increased traffic accidents;

Sulfur dioxide: Reduced visual range, inflammation of eyes. Odor, chest tightness, respiratory tract inflammation, dyspnea, pulmonary edema, rapid asphyxia and death;

Hydrogen sulfide: odor, nausea, vomiting, affecting human breathing, blood circulation, endocrine, digestive and nervous system, coma, poisoning and death;

Fluoride and hydrogen fluoride: Strong stimulation of eyes, nasal cavity and respiratory tract, causing tracheitis, pulmonary edema, skeletal fluorosis and enamel teeth;

Chlorine and hydrogen chloride: irritate eyes and upper respiratory tract, and cause toxic pulmonary edema in severe cases;

Nitrogen oxide: smells bad odor, bronchitis, tracheitis, pulmonary edema, emphysema, dyspnea, until death;

Photochemical smog: red eyes, poor vision, headache, chest pain, general pain, paralysis, pulmonary edema, severe death within 1 hour;

Hydrocarbons: skin and liver damage, carcinogenic death;

Lead: Neurasthenia, abdominal discomfort, fecal secretion, anemia, low memory;

Carbon monoxide: dizziness, headache, anemia, myocardial injury, central nervous paralysis, dyspnea, severe death within 1 hour.

What is the role of air quality sensors?

At present, all kinds of air quality sensors have been widely used in air quality testing instruments and air purification devices such as air purifiers. LUFTMY specializes in providing air quality sensors with infrared dust sensors and laser PM2.5 sensors, long life, multi-serial output, strong anti-interference ability, high quality, high precision, low power consumption, affordable price. Welcome customers to call for advice.

What are PM2.5 air quality sensors?

Infrared dust PM2.5 sensor GDS06 uses the principle of optical scattering to obtain the particle concentration. Through the conversion of optical path and circuit, the dust concentration in the detection range is measured. GDS06 has the characteristics of small size, high precision, low power consumption and short response time. The air quality sensor can be used in air purifier and so on.

Air quality sensor LD16 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. Laser air sensor LD16 has the characteristics of small size, high precision, strong anti-interference ability, low power consumption, long life, short response time of zero error alarm rate, etc. LD16 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.
