Carbon Dioxide Monitor Kit.Carbon Dioxide Monitor Kit.

The Aranet4 sensor is an innovative air quality monitor that measures carbon dioxide (CO2) level, temperature, relative humidity and atmospheric pressure. The device is suitable for monitoring the CO2 level at home, in school, office, or any other indoor environment to give an indication of how well-ventilated it is. Knowing the CO2 level can help you identify if you need to take steps to improve ventilation or remove pollutants to improve indoor air quality to lower the risk of airborne infections. Poor ventilation has also been shown to cause other general symptoms such as tiredness and headaches.
