Koldioxidsensor SCD41 + temperatur och RF

SCD41 is a high accuracy sensor that uses photoacoustic technology to tell you the precise proportion of carbon dioxide (in ppm) of the air that you're breathing. It can also measure temperature and relative humidity.

Too much carbon dioxide has all sorts of unpleasant effects on humans, such as turning up your tiredness levels and turning down your brain power. CO2 build-up is a useful indicator of how well ventilated a space is and also how many people are breathing the same air - a variable that's definitely worth tracking in homes, workplaces and schools at the moment. SCD41 is the extended range variant of this sensor which means it can detect very high levels of CO2 at up to 5,000 ppm, so it could potentially also be useful in industrial and laboratory settings.
