With the intrusion of smog, dust and industrial wastegas, air quality problems are becoming more and more serious, and indoor airmonitoring improvement is imperative. In recent years, the deterioration of airquality in the country, people are paying more and more attention to air quality, especially those living in densely populated areas of large cities.Some people even expect mobile phones to have air detection function, which can detect the air quality around them in real time, so that take necessary measures in a timely manner.
CO2 sensor (fresh air)
In the field of air environment monitoring, we all know that the content of carbon dioxide is of concern to many people. The carbon dioxide content is too high to accumulate in the body, leading to adecrease in pH, hypoxia, and even some dysfunction. After the CO2 sensor detects the content of carbon dioxide in the air, when the carbon dioxide content in the air exceeds a certain range, the air volume switch of the freshair system can be controlled by the controller to open the air volume switch ofthe fresh air system to exhaust the air.
PM2.5 sensor (clean air)
The PM2.5 sensor uses the principle of light scattering and particle counting technology to accurately detect the amount of micro-particles in the surrounding environment. The PM2.5 sensor automatically detects the content of PM2.5 particles in the air, and then can be used in the main control machine through software communication technology. Displayed on the client, it can also be applied in smart homes, intelligently linked with other devices. When the PM2.5 content in the air is too high, it can be linked to control the window opener to close the window and open the air purifier orthe fresh air system. Purify the air and make the living environment fresh and suitable forever.
Formaldehyde HCHO sensor (healthy air)
Formaldehyde HCHO sensor detects the formaldehyde present in the air through the diffusion principle, and also has a certain degree of response to gases such as alcohol, benzene and naphthalene. After detecting the concentration of formaldehyde in the air, it can be used in the host or customer through communication software technology. The display valueis displayed, and it can also be intelligently linked with other devices in the smart home to control the air purifier or the switch of the fresh air system to remove formaldehyde.
