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 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 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.
