This product has a high precision carbon dioxide infrared sensor, digital humidity and temperature sensor chip. It can detect and display CO2 levels of the surrounding environment and give a corresponding warning. The alarm can be mounted to a wall, or placed anywhere in a room. Please read manual before use, and store it carefully for future use and maintenance.
Function: The LED display shows CO2 concentration, ambient temperature and humidity. The alarm gives a voice broadcast when the CO2 concentration levels are too high.
CO2 concentration and display
This product can detect and display CO2 concentration of the surrounding environment and give a corresponding warning. The default warning value is 1000ppm, and the default alarm value is 1500ppm.
Carbon dioxide levels and guidelines
CO2 level | Description |
400ppm | Normal outdoor air level |
400-1000ppm | Typical level indoors with good ventilation. NOTE: if CO2 levels are low when building is sealed and occupied, check for overventilation. Too much fresh air causes energy to be wasted. |
1000ppm | Recommended maximum level in a closed room. Considered maximum comfort level. |
>1200ppm | Poor air quality, ventilation is required. |
2000 ppm | This level of CO2 concentration produces a significant increase in drowsiness, tiredness, headache, lower levels of concentration and increased likelihood of spreading respiratory viruses. |
>5000 ppm | Maximum allowed concentration within an 8 hour working period. |
Humidity level detection and guidelines
This product can detect and display humidity of the surrounding environment and give a corresponding warning. When humidity levels are too high (>90%RH) you hear a voice: "Humidity is abnormal". Ventilation is required.
Temperature level detection and guideline
This product can detect and display temperature of the surrounding environment and give a corresponding warning. When temperature levels are too low (<-5°C) or too high (>50°C) you hear a voice: "Temperature anomaly detected". Ventilation is required.

Touch button function
SET / AUTO
Default setting of the alarm is the display alters between temperature, humidity and CO2 level.
TEST/HUSH
Turning off the alarm
You can manually turn the alarm off, so it does not sound when values are too high.
Language setting
You can change the language of the voice by pressing the TEST / HUSH and SET / AUTO buttons simultaneously for 3 seconds. The language changes, long press again to go to the next language. Default language is English. The alarm supports German, French, Italian, Spanish and Dutch language.
Environmental light detection function
When the CO2 concentration, temperature and humidity are within normal range and the ambient brightness is very low (at night, indoor lights are all off), the brightness of the product's display screen and indicator will automatically decrease to reduce the impact on user's sleep.
Normal brightness is displayed when CO2 concentration, temperature or humidity is detected abnormal.
