Operation Manual

If you blow into the station, the humidity level raises!
What happens if the station gets soaked?
When the weather is really humid (pouring rain...) the humidity sensor can be temporarily saturated. It usually
takes a few hours to desaturate, and go back to normal.
CO2 measurement
By accumulation of gases from adhesives, cleaning products, smoke, dust, dust mites and mold in a confined
space, your indoor air can rapidly become unhealthy. The CO2 is produced by human activities and can
rapidly concentrate in confined spaces such as a living room, bed room, office... As CO2 level rises, so does
the concentration of unhealthy components of indoor air. CO2 level is therefore a good confinement and air
quality indicator. The CO2 level is measured by the station's indoor module.
For a direct read on the station, the light on the indoor module use the same color code: if you touch
to top of the indoor module, it briefly lights up and give you an indication of the actual CO2 level in
the room, with the same color code.
CO2 indicator
For a quick CO2 levels reading, the following color code is used:
- Green = good
- Yellow = Could be improved
- Red = Air should be ventilated.
This indicator is present in the application as a colorful gas bubble.
Units
CO2 is measured in ppm (parts per million), meaning the number of CO2 molecules among one million of air
molecules. Usual indoor CO2 levels vary between 400 and 5000 ppm.
Typical ppm values
- Outdoor, CO2 level is always around 400 ppm.
- In a room appropriately ventilated, CO2 level must stay below 1000 ppm.
- In a closed room such as a meeting room with a couple of person or a small bedroom at night, CO2 can
easily go pass 1000 ppm.
