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.A4 Amazon app bloks mobile3.jpg
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

  1. temperature indicator in °C or Fahrenheit
  2. indicator of % relative humidity
  3. CO2 concentration in ppm
  4. alarm indicator (activated in the app)
  5. CO2 risk level (3 positions)
  6. A indicates whether the CO2 sensor is automatically calibrated or not
  7. PRO indicates if you have the PRO version which communicates with an Aranet PRO base
  8. battery level indicator
  9. CO2 alert thresholds are configurable in the Aranet4 app
