Aranet4 Home Indoor Air Quality Monitor

About the Aranet4 monitor

Aranet4 monitor is an innovative wireless device for effortless monitoring of indoor air quality – CO², relative humidity, temperature 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 with a long battery life. Additionally, the device provides visual and optional buzzer notifications when the CO² concentration becomes unhealthy. CO² concentration levels of 1400 ppm (parts per million) and up are unhealthy and can cause drowsiness and decrease cognitive function by 50 %. A high concentration of CO² is an indicator of insufficient ventilation, which can increase the risk of infection with airborne diseases.

Aranet4 uses the nondispersive infrared (NDIR) sensor to measure the CO² concentration. The CO² gas in the chamber absorbs infrared light; this absorption is measured by the sensor. The
less light passes through, the higher the CO² concentration. CO² absorbs only a specific wavelength of light, therefore an optical filter is used.

Download the Aranet4 app and connect via Bluetooth with up to six devices. The app allows you to configure the Aranet4 device and access the data monitored by the device. Read a detailed description of all the possibilities that the app offers in the chapter “How to pair Aranet4 to my smart device using the Aranet4 app” on page 5. 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” on page 6. There are two Aranet4 models – Aranet4 HOME and Aranet4 PRO. You can find out more about how they differ in this informative leaflet. Measurement and data transmission** intervals are 1,2,5, or 10 minutes.
The default measurement interval is set to 5 minutes.

• Atmospheric pressure data measurements are available only on the Aranet4 app.
  More information is in the chapter “How to pair the Aranet4 to my smart device using the Aranet4 app” on page 5.

• For Aranet4 PRO paired to Aranet PRO base station.

The Aranet4 sensor screen explained

1. The temperature of the air in Celsius or Fahrenheit. To change the temperature units, refer to the chapter
   “Switch positions explained” on page 4.

2. Relative humidity of the air (RH %).

3. CO² concentration level in ppm (parts per million).

4. Buzzer status.
   The speaker symbol is visible when the buzzer is enabled. The buzzer’s settings can be adjusted using the Aranet4 app.

5. CO² threshold level indication
   Green represents a good CO² level (below 1000 ppm) Yellow represents the average CO² level (1000 to 1400 ppm)
   Red represents an unhealthy CO² level (above 1400 ppm*)

6. CO² calibration mode indication. Symbol is displayed when calibration is set to automatic. No letter is displayed when calibration is set to manual mode.

7. For Aranet4 PRO only: Monitor identification number comprising five hexadecimal symbols of the Aranet4 PRO device (wirelessly connecting Aranet PRO base station & Aranet Cloud).

8. Battery level.

9. Adjustable CO² thresholds that can be set using the Aranet4 app.
   These are default thresholds that can be reconfigured using the Aranet4 app.

Aranet4 screen indications

1. The inverted screen alerts when CO² concentration has reached the red threshold level.
2. Do not remove batteries during a firmware upgrade.
3. The batteries are empty. Replace them.
4. The calibration progress.
5. Six-digit pin code displayed for wirelessly connecting the device with your smartphone to the Aranet4 app via Bluetooth.
6. Temperature below zero can damage the sensor. The recommended operating temperature of the sensor is 0 °C to 50 °C (32 °F to 122 °F).

CO² calibration

The Aranet4 monitor is calibrated at the factory. However, the user can carry out CO² calibration manually when needed. The general recommendation is to calibrate Aranet4 once a year, but more often if it is used in dusty environments. During the manual calibration, the Aranet4 device must be exposed to fresh outdoor air. Keep a distance of at least one meter from the device during the calibration process – no humans, animals, or plants should be closer to the device during calibration. You can calibrate your Aranet4 manually with or without the app. To manually calibrate Aranet4 with the Aranet4 app, pair your device with your smartphone (refer to the chapter “How to pair Aranet4 to my smart device using the Aranet4 app” on page 5), open Settings, and choose CO² calibration.
You can also calibrate the Aranet4 monitor manually without the app. To perform the manual
CO² calibration, flip the switch from MANUAL to AUTO and then back to MANUAL (flip the switch quickly, with less than one second between each movement). Once started, the
calibration progress will be displayed on the screen of the device. In case of a calibration failure message, make sure that the device is still in a fresh air environment and repeat the process from the beginning. To learn more about the switch positions, see the next chapter “Switch positions explained” on page 4. If the automatic calibration mode is used, the Aranet4 device needs to be exposed to fresh air at around 420 ppm (for instance, outdoors) for at least 8 hours each month.

Switch positions explained

The Aranet4 monitor has four small configuration switches that allow the user to adjust the settings.
To access the configuration switches, open the cover of the battery compartment on the back of the device. With the batteries remaining inside, adjust the switch position (up or down) using the pin tool supplied with the Aranet4 device. You can adjust the switches with the batteries removed as well, but note that, if you remove the batteries, it will erase the measurement history from Aranet4 memory. To avoid this, update the data in the Aranet4 app before removing the batteries. The new settings will start working once the batteries are back in. The positions of the configuration switches have the following meaning:

Switch tool (PIN) can be found in Aranet4 Quick Start Guide english version.
