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.
