ARANET — MAKING SENSORS WIRELESS
Monitors air quality at your home, school, office or any
other indoor private or public spaces.
USER MANUAL
Aranet4 HOME,
Aranet4 PRO

The Aranet4 sensor is a battery powered CO²meter with additional measurements of
temperature, relative humidity and atmospheric pressure. *The device is suitable for
monitoring the CO² level at home, in school, office or any other indoor environment.
Measurement data is displayed on a power-efficient e-ink screen allowing for long battery life.
Additionally the device can provide visual and sound notifications in case of the CO²
concentration becomes unhealthy. The high concentration level of 1400 ppm (parts per
million) – level typically associated with complaints of drowsiness and poor air quality.
By using the Aranet4 app on your smart device it is possible to wirelessly access real-time
data and up to one week of historical measurement data. The app also allows you to
configure the Aranet4 device. The Aranet4 app supports connection of several Aranet4
sensors to monitor their parameters remotely from a single smart device.
Additionally up to 100 Aranet4 PRO devices can be connected to the Aranet PRO base station.
Refer to the chapter Using Aranet4 device with the Aranet PRO base station.
Data transmission interval: 1, 2, 5 or 10 minutes.
Default measurement interval is set to 5 minutes.
Aranet4 uses the nondispersive infrared (NDIR) sensor to measure the concentration of CO².
The CO²gas in the chamber absorbs infrared light and this absorption is measured by the
sensor. The less light passes through – the higher the CO²concentration. The CO²gas absorbs
only a specific wavelength of the light therefore an optical filter is used.

The Aranet4 device is calibrated at the factory. However, the user can perform CO²
calibration manually when needed. During the manual calibration the Aranet4 device
must be exposed to fresh air (about 420 ppm of CO²) and the environment should be
stable (not changing). Maintain a distance of at least 1 meter from the device during
the calibration process.
To start the manual CO²calibration, change the position of the switch (see next
chapter Switch positions explained)from MANUAL to AUTO and then back to
MANUAL (maintain maximum of 1 second between each movement).
The calibration progress will be displayed on the screen of the device. In case of a
calibration failure message, make sure that the environment requirements are met
and repeat the process from the beginning.
Manual calibration can be done using the Aranet4 app as well.
In case of automatic calibration mode, the Aranet4 device needs to be exposed to a
fresh air at around 420 ppm (for instance, outdoors or room with good air exchange)
at least 8 hours each month.

The Aranet4 device has four small configuration
switches that allow the user to adjust the
preferences of the device.
To access the configuration switches, open the
cover of the battery compartment on the back of
the device. While batteries remain inserted, adjust
the switch position (up or down) using the pin tool
that is supplied with the Aranet4 device (or any
other suitable thin tool).
Switches can be adjusted while batteries are
removed as well, but note that if you remove
the batteries, the measurement history will be
erased from Aranet4 memory. The changed
preference setting will be enabled once the
batteries are inserted back in.

Using Aranet4 PRO device with the Aranet PRO
base station
The Aranet PRO base station serves as a device for collecting, storing and maintaining data
from all types of Aranet sensors, including Aranet4 PRO. Up to 100 sensors can be connected
to a single Aranet PRO base station which has a capacity to store the measurement history up
to 10 years.
To connect the Aranet4 PRO to the Aranet PRO base station, initiate the sensor pairing mode
on the Aranet PRO base station and start the pairing on the Aranet4 device by changing the
switch position from disable (0) to enable (radio symbol). Alternatively, while switch is in the
enable position (radio symbol on screen is visible), remove and reinsert the batteries. Please
note, that by removing the batteries, the measurement history will be erased from the
Aranet4 memory.
