DESCRIPTION This board provides a sensor for CO2, temperature and Relative Humidity measurements to a BBC micro:bit. FEATURES CO2 Concentrations So, what do these readings mean? Fresh outdoor air should give a reading of around 400. In a smallish room with a few people in it, this will rapidly rise above 1000, as peopl
03-06-2018 · DS18B20 Pre-wired waterproof digital temperature sensor. Hardware Details. For the pre-wired sensor: Red connects to 3V-5V, Blue/Black connects to ground, and Yellow/White is data. Hardware Connections. Use a 4.7K resistor as pull-up for the data pin. The Microbit has to both read from and write to the data pin of the DS1820.

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.
