Q4. How high is the concentration of carbon dioxide in the air?
Carbon dioxide (CO2) classification guidelines:
Non-mandatory reference grading:
a )250 ~ 350ppm-usual outdoor air level.
B) 350 to 1,000ppm-typical in well-ventilated living spaces.
c) 1,000 to 2,000ppm-insufficient oxygen, drowsy enough to cause a complaint
d ) 2,000 to 5,000ppm-stagnant, old, stuffy air level. Headache, lethargy, accompanied by lack of concentration, decreased attention, rapid heartbeat and mild nausea.
e) > 5,000 ppm-exposure to which may result in severe hypoxia, permanent brain damage, coma and even death.
For the sensor, 400ppm is the concentration value of carbon dioxide in the fresh air environment. When the number of people gathered in the room or the concentration of carbon dioxide in the closed room will gradually increase, which will lead to hypoxia and other conditions, it is recommended to keep the closed room or the indoor with an increased number of people Ventilation, so as not to cause sultry, irritability, headache and other reactions!
