1. Introduction
Aura-CO2 is a five-year battery-operated CO2 monitor that measures in real time
Carbone Dioxide concentration, temperature, pressure and relative humidity. Data is
displayed on a large e-Paper screen and on the online dashboard when Aura-CO2 is
connected to the LoraWAN network. End users can customize sound & visual alarms
through the eLichens Aura smartphone application.
Aura-CO2 embeds the eLichens Foxberry CO2 gas sensor, a cutting-edge dual-
channel NDIR (Non-dispersive Infrared) gas sensor integrated in a small and compact
form factor. It is based on eLichens’ patented technology including a proprietary IR
micro-source, patented optical design and advanced signal processing algorithms.
Using the auto calibrated Foxberry gas sensor ultra-low power mode, Aura-CO2
reaches more than 5 years on battery without recharging, maintenance or calibration.
Studies showed that there is a relationship between the ambient CO2 level
and the need for air renewal. The CO2 level is linked to the number of people
in a room. The higher the level, the greater the risk of transmission of
pathogens and viruses such as coronavirus. Aura-CO2 alerts you when the
CO2 level is too high. By optimally adjusting the ventilation and air conditioning system,
the user can ensure good indoor air quality at all times and prevent the transmission
of pathogens. This reduces the risk of infection by diseases such as COVID-19.
