Air Quality Monitor

The Air Quality Index ( AQI) can be categorized from Good to dangerous. AQI would state as Good when the range is between 0 to 50. When the AQI is between 51 to 100, it will state Moderate to alert us that the air quality might cause health concerns for certain group of people.

In general, the relative humidity value is 50%, but the optimal value is different in every room. The value in living, sleeping and working rooms should be between 40-60%, in the kitchen between 50-60% and in the bathroom between 50-70%.

Particulate matter (PM) refers to tiny particles or droplets in the air with a diameter of 2.5 micrometers or less. PM 2.5 are so tiny that they can enter the Bronchia and the Alveoli, while the PM 10 can only reach the nasal cavity, its just the matter of the size between PM 10 and PM 2.5. Both can be associated with health concern issues, since the particles are so small that can transmit deeper into our respiratory system.

When the CO² level is at under 1,000 ppm it will be categorized as Good. As long as CO² level is under 2,000 ppm it will still be categorized as normal. However, when the CO² level is over 2,000 ppm then it might be cause headaches, sleepiness, and feeling of stuffy air.

The carbon dioxide (CO²) concentration is measured in ppm. Ppm is the abbreviation for “parts per million” i.e. 1 ppm = 1 times 10^-6. Carbon dioxide levels can rise very quickly in poorly ventilated rooms.

VOCs are volatile organic compounds that are usually used for indoor air quality assessment, for which there are recommendations from the Federal Environment Agency (Umweltbundesamtes) with regard to the maximum values. VOC are gaseous and vaporous substances of organic origin in the air at room temperature or higher temperatures. VOCs include aldehydes, alcohol, hydrocarbons, benzene, but also many other organic compounds that are formed in biological processes.

TVOC – Total Volatile Organic Compounds

TVOC can be explained as all the VOCs added up together. To be simple, TVOC are a group of thousands of organic chemicals that evaporate at low temperatures.

The Air Quality Monitor is a multifunctional product which can detect:

• Carbon dioxide (CO² )
• Total Volatile Organic Compounds (TVOC)
• Particulate Matter 2.5, 1.0, 10 
• Air quality index
• Temperature
• Humidity

The air quality detection device, combines multiple air sensors with a built-in fan to allow real-time monitoring of Carbon dioxide (CO² ), Total Volatile Organic Compounds (TVOC), PM 2.5, PM 10, PM 1.0, temperature and humidity on its digital LED display.
