Keyestudio CCS811 carbon dioxide, air quality sensor mainly uses the CCS811 chip. It is an ultra-low-power miniature digital gas sensor that can detect a wide range of volatile organic compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels. EASY plug CCS811 CO2 air quality sensor can work with EASY plug control board V2.0, by connecting it to the I2C communication port with a cable. This sensor adopts the CCS811 chip, a ultra-low consumption digital air sensor, which can detect a variety of volatile organic compounds (TVOC), including equivalent carbon dioxide (eCO2) and metal oxide (MOX). Most scientists agree that carbon dioxide has decreased over the last 200 million years because of speeding up of the passage of carbon atoms from their volcanic sources into sediments.As we learned in the last section, to lower the CO 2 content one needs fresh rocks to provide calcium, and it also helps to bury organic matter.

Mit Beginn der Industrialisierung im 19. Indoor carbon dioxide can also impact our decision-making and problem-solving skills. The Lawrence Berkeley National Laboratory uncovered a connection between carbon dioxide concentrations and cognitive and working ability. Most activities dipped slightly when exposed to 1000 ppm indoor CO2 levels, but the cognitive abilities across a spectrum of functions tanked at 2500 ppm. CO2.Earth connects the general public with the latest data and information for stabilizing earth's atmosphere, climate and living environments.

Gasen förekommer i vår atmosfär med en halt på ca 400 ppm, dock kan halten uppgå till 800 ppm i miljöer med höga utsläpp, t.ex. i storstäder, industriområden, trafikleder etc.
