Wireless indoor air quality monitor
USER MANUAL
& DATASHEET
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 CO²level in
indoor environments such as at home, in office or at school.
Measurement data are displayed on power-efficient e-ink screen allowing for long battery life.
Additionally the device can provide a visual and sound notifications in case the CO²level surpasses the
high concentration level of 1400 ppm (parts per million) – level typically associated with complaints of
drowsiness and poor air quality.
Aranet4 uses the nondispersive infrared (NDIR) sensor to measure the concentration of CO². The CO²
gas in the chamber absorbs infrared light and this absorption is measured by the sensor. The less light
passes through – the higher the CO²concentration. The CO² gas absorbs only a specific wavelength of
the light therefore an optical filter is used.
By using the Aranet4 app on your smart device it is possible to wirelessly access the real-time data and
up to one week of historical measurement data. The app also allows 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.

The positions of the configuration switches have the
following meaning:
AUTO / MANUAL – switch the CO²calibration mode
to either manual (default position) or automatic mode.
Use MANUAL calibration mode in case you are not
certain which mode to use.
°C / °F – switch between either Celsius or Fahrenheit
degrees.
Bluetooth / 0 – enable or disable (0) the
Bluetooth connectivity.
Aranet radio / 0 *– enable or disable (0) the
Aranet radio connectivity. Refer to chapter Using
Aranet4 device with the Aranet PRO base station.
*Function available only in Aranet4 PRO.
CO²threshold level indication.
When the human mode of the CO²
indication is selected:
Green represents normal level
(below 1000 ppm)
Yellow represents average level
(1000 to 1400 ppm)
Red represents high level
(above 1400 ppm)
When the plant mode is selected:
Green represents normal level
(above 500 ppm)
Yellow represents average level
(500 to 300 ppm)
Red represents low level
(below 300 ppm)
CO²calibration mode indication. Symbol
“A” is displayed when calibration is set to
automatic. No letter is displayed when
calibration is set to manual mode.

Radio status.*If the radio symbol is visible,
the connectivity with Aranet PRO base station
is enabled. Refer to switch positions of the
Aranet4 in chapter Switch positions
explained.
CO²indication mode. If the leaf symbol is
visible the CO²level indication is set to plant
mode (plants require higher CO²level than
humans). If the leaf symbol is not visible,
then CO²level indication is set to human
mode. You can select the mode using the
Aranet4 app.
Bluetooth status. If the Bluetooth symbol is
visible the Bluetooth pairing function is
enabled. Refer to switch positions of the
Aranet4 in chapter Switch positions
explained. Make sure Bluetooth connectivity
is enabled on your smart device in order to
connect to the Aranet4 device.

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.
Switch positions
explained

The Aranet4 device is calibrated at the factory. However, the user can perform CO²calibration
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 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 once a week.

Connect your smartphone with the Aranet4
device via Bluetooth by using iOS or Andoid
(access to device’s location should be allowed due
to general requirement for Bluetooth apps to
work correctly on Android OS) app to:
The Aranet4 device can be connected to a smart
device using the Bluetooth connection and the
Aranet4 app on either iPhone or Android. Make
sure Bluetooth connectivity is enabled on your
smart device and on your Aranet4 device.
To connect your Aranet4 device to your smart
device do the following steps:
How to pair Aranet4 to my smart device?
Launch the Aranet4 app and on the main
page (My devices) add a new device by
clicking on the (+) symbol.
Select your Aranet4 device from the list.
When prompted, confirm the start of
pairing.

Using Aranet4 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. 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 device to the Aranet PRO base station, initiate the sensor pairing mode on
3

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.
Find out more about the Aranet PRO base station at aranet.com and follow the User Guide on how to
pair Aranet sensors to the Aranet PRO base station.
