Aranet4 – innovative wireless CO2 monitoring solution

The Aranet team has developed Aranet4 – an innovative, standalone device for effortless monitoring of indoor air quality – CO2, temperature, relative humidity and atmospheric pressure.


Several studies have found that one of the main reasons for poor well-being is the high concentration of carbon dioxide (CO2) indoors. It makes people anxious, sleepy and unable to concentrate. The U.S. Environmental Protection Agency (EPA) studies indicate that indoor levels of pollutants may be even five times higher than outdoors. Another study from Harvard University demonstrated that a heightened CO2 concentration reduces the brain’s cognitive abilities by 50%. These are the core abilities your brain uses to think, read, learn, remember, reason, and pay attention. Therefore, it is very important to ensure sufficient air circulation in rooms where people stay for extended periods of time.


The Aranet4 wireless sensor is a simple and exciting way to monitor indoor air quality – it is small, portable, easy to operate and lets you know when the monitored levels have become unhealthy. You can take this fancy gadget wherever you go and always be aware of air quality around you. The device also has a power-efficient e-ink display thus ensuring extremely long battery life.


Aranet4 is designed for personal as well as business needs. It can be used daily for air monitoring at home, or up to 100 Aranet4 devices can be placed in multiple rooms and wirelessly connected to an Aranet PRO base station thus ensuring climate monitoring on an industrial level – in schools, hotels and other places.


Aranet4 has a handy smartphone app created for historical data access, atmospheric pressure monitoring and advanced device configuration.



Aranet PRO base station offers centralized data gathering and real-time viewing as well as unlimited historical information and alert functionality for larger sensor networks. It gathers readings from up to 100 Aranet sensors and can store data locally and on the Aranet Cloud.
