The Aranet4 HOME uses a non-dispersive infra-red sensor (NDIR) to measure CO2 concentration, along with additional sensors for temperature, relative humidity, and atmospheric pressure, precisely and in real-time. An e-ink display shows constant readings, along with a quick-glance color indicator that rates the air quality as good, average, or unhealthy. If the CO2 concentration in your home becomes too high, the Aranet4 HOME emits visual and audible warnings, alerting you to GTFO. Also, contact the gas company. Or, as the authorities have been warning you for the past three days, evacuate because you are in the line of a forest fire.


Or maybe you just live in a place where the air quality is awful but you can’t afford to move, and the Aranet4 HOME will end up just feeding you negative news you can’t change, making you feel as bad as your air quality.
