Air pollution is becoming more and more serious.With the emergence of the word PM2.5, people begin to pay more and more attention to the environmental problems in our lives.PM2.5 refers to particles with an aerodynamic equivalent diameter of less than or equal to 2.5m in ambient air, also known as fine particles.The higher the value, the worse the air pollution.The haze weather is caused by the fine suspended particles of PM2.5.Handheld air quality monitors can help us check the air quality of the surrounding environment, showing the concentration of carbon dioxide in the air, temperature and humidity, as well as the value of PM2.5.Handheld air quality detector can be used in buildings, workshops, mines, pig farms and other fields.What are the sensors in the air quality meter?
Temperature and humidity sensor
The temperature and humidity sensors used in air quality testing instruments can accurately measure the temperature and humidity in the air.The humidity sensor has high sensitivity, fast reaction time, stable and reliable performance.
Carbon dioxide sensor
If indoor gather a lot of people, and the air is not circulating, can make the oxygen content in the air relatively reduce, produce a large amount of carbon dioxide, indoor personnel will appear different degrees of poisoning symptoms.The co2 sensor can transmit the measured co2 concentration to the air quality detector through digital or analog signals.
There are also dust sensors in the air quality detector to measure the concentration of PM2.5 Luftmy recommends the LD11 laser dust sensor, which can be installed in the air quality detector to achieve accurate measurement of dust concentration in the air.The laser dust sensor USES optical method to detect the dust concentration in the air. It has the advantages of small size, easy installation, anti-interference and low noise.
