This board, designed for use with the Lets Talk Science Living Space Project, provides a CO2, temperature and Relative Humidity measurements to a BBC micro:bit (not included). We include a 9V battery clip adapter with the CO2 sensor (battery not included).
Visit the Lets Talk Science Living Space Project for more information and all sorts of useful resources and lesson plans.
Important! When powered by batteries, the CO2 sensor will provide power back to the micro:bit. Make sure you have the power leads connected correctly between the CO2 sensor board and the micro:bit or your micro:bit could be damaged!
Note: Micro:bit and crocodile clips not included
