The Aranet4 is an innovative, self-contained, battery-powered wireless sensor for monitoring CO2, temperature, relative humidity and air pressure in the home, school, office or other indoor environment. The device is portable, simple to install, easy to use and lets you know when the monitored levels have become unhealthy.
The Aranet4 sensor/display module can be simply placed on a table or hung on a wall. It is battery operated (approx. 4 years maximum) and therefore does not require any connection. Data transmission for the HOME model is via Bluetooth to the free aranet app on your smartphone. Measurements are taken at the frequency of your choice (1, 2, 5, 10 minutes).
The reading of the risk level on the display is simplified by the colour codes:
green: all is well CO2 > 1000ppm
yellow: level between 1000 and 1400ppm
red: high carbon dioxide level >1400ppm
temperature indicator in °C or Fahrenheit
indicator of % relative humidity
CO2 concentration in ppm
alarm indicator (activated in the app)
CO2 risk level (3 positions)
A indicates whether the CO2 sensor is automatically calibrated or not
PRO indicates if you have the PRO version which communicates with an Aranet PRO base
battery level indicator
CO2 alert thresholds are configurable in the Aranet4 app
