Default CO2 alarm level (Unit: ppm) :

1. (CO2< 800) no alarm, display smiling face to remind that the ernvironmental CO2 concentration is low and the living environment is comfortable
2. (800 < CO2 < 1200) no alarm, smiling expression indicates that the ervironmental CO2 concentration is moderate
3. (1200 < CO2 < 1500) no alarm, uncomfortable expression indicates that the ervironment is not good enough
4. (1500 < CO2 < 3500) the alarm sound (drip, drip, drip) sounds three times, indicating that the CO2 concentration is relatively high and it is not suitable for people to live
5. (3500 < CO2 < 5000) the alarm sound (drip, drip, drip, drip, drip) sounds 6 times, indicating that the CO2 concentration is very high. Please pay attention to environmental safety
6. (5000 < CO2) when the concentration reaches 5000, the buzzer keeps alarming,indicating that the CO2 concentration is extremely high and the ervironment is dangerous
