The Aranet4 sensor is an indoor air quality monitor that measures carbon dioxide (CO₂) levels, temperature, relative humidity, and atmospheric pressure. It can be used at home, in schools, offices, or other indoor environments to help assess how well a space is ventilated.
Monitoring CO₂ levels can indicate when ventilation may need to be improved or when steps should be taken to reduce indoor pollutants. Poor ventilation has been associated with increased risk of airborne infection transmission, as well as general symptoms such as fatigue and headaches.
Please Note: These devices are not carbon monoxide detectors and are not life safety devices.
The Aranet4 CO2 Monitor Lending Program at the Okanagan Regional Library is generously supported by Community Access to Ventilation Information (CAVI).
