USER MANUAL
WHAT IS THE ARANET4 DEVICE?
The Aranet4 sensor is a battery-powered CO₂ meter with additional measurements
of temperature, relative humidity, and atmospheric pressure. * The device is
suitable for monitoring the CO₂ level in indoor environments such as at home,
in office, or at school.
Measurement data are displayed on power-efficient e-ink screens allowing for
long battery life.
Additionally, the device can provide visual and sound notifications in case the
CO₂ level surpasses the high concentration level of 1400 ppm (parts per
million) – a 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 CO₂ concentration. 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
the 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 ARPANET PRO
BASE STATION.
- Atmospheric pressure data measurements are available only on the Aranet4 app. More information in chapter HOW TO PAIR THE ARANET4 TO MY SMART DEVICE.
THE ARANET4 SENSOR SCREEN EXPLAINED
-
CO₂ concentration level in ppm (parts per million).
-
The temperature of the air in Celsius or Fahrenheit. Refer to the switch positions of the Aranet4 in chapter SWITCH POSITIONS EXPLAINED.
-
Relative humidity of the air (RH %).
-
Battery level.
-
Alarm status. The speaker symbol is visible when the alarm function is activated. The alarm settings can be adjusted 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.
-
Radio status.* If the radio symbol is visible, the connectivity with the Aranet PRO base station is enabled. Refer to switch positions of the Aranet4 in chapter SWITCH POSITIONS EXPLAINED.
-
CO₂ indication mode. If the leaf symbol is visible the CO₂ level indication is set to plant mode (plants require a higher CO₂ level than humans). If the leaf symbol is not visible, then the CO₂ level indication is set to human mode. You can select the mode using the Aranet4 app.
-
CO₂ threshold level indication. When the human mode of the CO₂ the indication is selected:
**Green represents the normal level (below 1000 ppm)
Yellow represents the average level (1000 to 1400 ppm)
Red represents a high level (above 1400 ppm)
When the plant mode is selected:
**Green represents a normal level (above 500 ppm)
Yellow represents the average level (500 to 300 ppm)
Red represents a low level (below 300 ppm) -
CO₂ calibration mode indication. Symbol “A” is displayed when calibration is set to automatic. No letter is displayed when calibration is set to manual mode.
SWITCH POSITIONS EXPLAINED
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.
The positions of the configuration switches have the following meaning:
CO₂ CALIBRATION
The Aranet4 device is calibrated at the factory. However, the user can perform CO₂ calibration manually when needed. During the manual calibration, the ranet4 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 CO₂ calibration, change the position of the switch from MANUAL to AUTO and then back to MANUAL (maintain a 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 environmental requirements are met and repeat the process from the beginning. Manual calibration can be done using the Aranet4 app as well. In the case of automatic calibration mode, the Aranet4 device needs to be exposed to fresh air at around 420 ppm (for instance, outdoors or room with good air exchange) at least once a week.
HOW TO PAIR ARANET4 TO MY SMART DEVICE?
Connect your smartphone with the Aranet4 device via Bluetooth by using iOS or Android app to:
Access real-time measurement data overview
View seven-day measurement history
Set alarms and frequency of sensor readings
View atmospheric pressure monitoring
Access all nearby Aranet4 devices
****Do the CO₂ calibration of the device
Get access to the available firmware updates
Your mobile phone must have either Android 6.0 or newer (for Android) or iOS 11.00 or newer (for iPhone) in order for you to be able to download the app.
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:
1 Launch the Aranet4 app and on the main page (My devices) add a new device by
clicking on the (+) symbol.
2 Select your Aranet4 device from the list.
3 When prompted, confirm the start of pairing.
4 Type in the 6 digit passcode that is shown on the display of your Aranet4
device.
USING ARANET4 DEVICE WITH THE ARPANET 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 of up to 10 years.
To connect the Aranet4 device 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 the 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.
