D. Function and effect description 1. TVOC/CO2/PM2.5 data  CO2 1000ppm means that the air concentration of carbon dioxide reaches 1%  The detection of CO content in serum (plasma) is one of the indexes of metabolic acidity and alkalinity, which basically represents the situation of acid-alkali reserves in plasma. When the volume fraction of carbon dioxide in the air is 1%, I feel stuffy, dizzy and palpitation; 4%-5% feel dizzy; More than 6% will make people delirious, gradually stop breathing and cause death. The density of carbon dioxide is higher than that of air. When carbon dioxide is low, it is harmless to human body, but when it exceeds a certain amount, it will affect people's breathing (other organisms too). The reason is that the concentration of carbonic acid in blood increases, acidity increases, and acidosis occurs. 2. IAQ air quality grade  GOOD: when all five indicators are Good, the IAQ level is GOOD, and the LED lights are green.  Poor: When any of the five indicators is POOR, IAQ level is POOR, and the LED lights are red.  Moderate: others are Moderate, and the LED lights are yellow. 3. Temperature and humidity function:  Indoor temperature range: -9°C ~ 50°C, HH.H is displayed above 50°C, and LL. L is displayed below-9°C;  Indoor humidity range: 20-99%; More than 99% show HH and less than 20% show LL;  Indoor temperature detection period: 60 seconds. 4. The LED lighting backlight conditions:  Fire DC power supply, after power-on or RESET, LED highlights; Good Moderate Poor PM2.5 0-15 ug/m³ 15-40 ug/m³ >40 ug/m³ PM10 0-20 ug/m³ 20-100 ug/m³ >100 ug/m³ CO2 0～800ppm 800～1000ppm >1000ppm HCHO 0-30 ug/m³ 30-100 ug/m³ >100 ug/m³ TVOC 0-200 ug/m³ 200-600 ug/m³ >600 ug/m³ GE22-3007a-PM2.5-PM10-CO2-HCHO-TVOC-temperature-humidity 7-in-one product specification Ver.: R3  Dry battery power supply, power on or press [TOUCH] alone, the LED will highlight for 30 seconds, and then turn off. 5.
