Developer's Description

Connecting your smartphone and Aranet4 device via Bluetooth, a handy Aranet4 app allows you to remotely view current and historical measurement data and adjust the configuration of the device.

Aranet4 is a simple, easy to use, battery powered CO2 monitoring device. It displays on its screen the current value of CO2 concentration, as well as the temperature, relative humidity and atmospheric pressure. The three colors on the screen indicate when the CO2 limits exceed norms and action to increase the air circulation must be taken.
