The Aranet4 HOME sensor is a battery powered, wireless Bluetooth device. Finally a CO2 monitor that is simple to install. The traffic light system lets you know when CO2 levels have become unhealthy. Google play and Apple Store Apps allow the user to set up and use the product within minutes. You can alter settings to suit your needs using the App.

We love the Aranet4 CO2 monitor. Firstly, this all in one CO2, temperature, RH and atmospheric pressure sensor solution! In addition the portable sensor can be with you in the car, out and about as well as in your home or place of work. The clear display makes air quality easily visible at a glance so you can reactively improve the air quality when required while also monitoring the history via the App.

To stop thieves, the Aranet4 HOME has an anti-theft wall mount (sold separately). The wall mount uses a Security screw that needs a screwdriver with a Torx T15 insert bit to remove it.

The other version is the Aranet4 PRO version is the sensor is compatible with Aranet Cloud.
