Why calibrating the sensor ?
The CO2 level
performed using
technology (NDIR:
infrared). This technology has a
drift that the sensor automatically
compensates for using an ABC
(Automatic Baseline
method, which eliminates the need for
manual maintenance and maintains
accuracy of CO2
throughout the life of the sensor.
This method is effective and reliable
in a typical environment, where the
CO2 level reaches its minimum level
(400 ppm) during a few hours (night
and weekend for premises, daytime in
a room).
This calibration
automatically every 8 days.

How do I calibrate the sensor ?
You can also perform a manual
calibration. To do this :
- Place your sensor near an open
window or outside for at least 2
minutes
- Press the button on the back of the
sensor for 5 seconds
The orange LED on the back of the
sensor will be steady for the duration
of the calibration. It then turns green
for 5 seconds when calibration is
complete.
End of battery life
It is possible to monitor the battery
status on the dedicated application,
throughout the life of the product. On
the product, the end of battery life is
indicated if no event is triggered when
a button is pressed. As soon as the
battery is empty, it must be replaced.
