Connected Inventions AirWits CO2 is a
wireless air quality metering device with
ultra long battery life. This intelligent and
small device measures and sends the
CO2, temperature and humidity data
sequentially from 10 min to 24 hours
using the world-wide Sigfox IoT-network
connectivity for data transmission,
enabling very low lifetime cost. The
installation of the device is extremely
simple procedure and requires neither
special tools nor configuration operation.
The device is maintenance free, and thus a
great solution especially for long term
indoor air quality metering providing
accurate data for energy savings and
comfortable living conditions which can
be monitored remotely. By default, the
device calibrates itself every 48 hours yet
it offers different calibration features for
advanced use, when needed.

The basic functionality procedure example:!
Function
When the device is powered on, it will do initial CO2 measurement calibration within 30
minutes. For this time, place the sensor in fresh air environment clear from any human,
gas or petrol operated devices, stoves, burning objects or animals as the initial
calibration target is 400ppm CO2. After calibration is ready, the device will send the
initial measurements and ask downlink message from the network. The CO2 Baseline,
transmission interval time and adaptive power control function can be set through
downlink message. In case the downlink message is not in use, the device continues to
send a measurement message every 30 minutes and request downlink message every
24 hours.

Assembly & Installation
!
Save the identifier and the key
of the device. The identifier
and the PAC key is on the label
on the bottom of the device.
Yo u c a n a l s o r e a d t h e
identifier and the PAC key
using the QR code.
!
Move the device to fresh air
location and switch the device
on by sliding the power switch
to position “1”
!
Install the wall plate to the
wall using screws suitable for
the wall material. Please
note the orientation!
!
Attach the device to the wall
having the pins meeting
installation holes in the
device. Please note the
orientation!

The device needs to be calibrated.
During the first 24 hours of initialisation
the device needs minimum of 1 hour of
fresh air in order to work properly. This
means that the device needs a
minimum of 1 hour after initialisation in
an environment without any CO2
Please note! Avoid placing device
closer than 15cm on any metal or
magnetic object, electric cables,
electric devices or selective glass
as this will dramatically reduce
radio performance as well as
battery life of the device.!
!
Replacing batteries
The device battery pack is proprietary made. Once device runs out of battery, please
contact your local partner or Connected Inventions for support the battery pack
replacement. Do not try to replace the battery pack with other brands available as there
is a risk of breaking the device. The battery pack lasts years in normal use so in case of
no messages received from the device, please check first the power is switched on and
the Sigfox radio coverage is available at the location.
