What is Neko ?
Neko is a detector that measures the CO2 level in a room and alerts on 4 levels:
- <430 PPM: this is the reference level corresponding to an outdoor environment.
- <800 PPM : air considered as quality air
- between 800 and 1000 PPM : the room must be aerated
- between 1000 and 1500 PPM: poor quality, the room must be aerated
- >1500 PPM: Warning! very bad quality of the air in the room
By following the instructions given by Neko, you will promote the ventilation of a room and thus reduce the risk of aerosolidation contamination by the COVID19 virus.
How to make Neko ?
Neko can be manufactured in a fab-lab or at a private home with some facilities (3D printer, ...). It does not require the manufacture of a printed circuit board.

Neko uses a Senseair S8 CO2 sensor which seems to us well adapted for this use. It is reliable, simple to implement and inexpensive (20-30 €).
