CO2 Mini Kit for micro:bit _RPI_CAB_ETH Working Temperature: -10℃ ~ ＋70℃This CO2 sensor board connects to the micro: bit through ring connectors and functions as a true CO2 sensor, providing accurate measurements of CO2 levels, temperature, and relative humidity. To make things more helpful when working out the different levels of CO2, the LED produces three different colours Green, Orange and Red. It also includes reverse polarity protection, adding an extra layer of safety to your setup. Note: micro: bit is NOT included
