Co2 sensor til micro:bit - Frederiksen Scientific

Denne CO2 sensor giver en måling af dels CO2, temperatur og relativ fugtighed til en micro:bit. 1) Indtast den scratch-kode som ses i billede 2. 2) Når programmet er uploadet, vil tryk på knap A vise CO2-niveauet i dele pr. Million CO2. Ved at trykke på knap B vises temperaturen i grader C, og begge knapper sammen viser den relative fugtighed.
