CO2 SENSOR FOR MICRO:BIT - MonkMakes

* Power - The CO2 part of the sensor module will not work reliably if the micro:bit is powered from a 3V battery pack. It should be powered either by USB, or from a 9V battery (or 6V battery pack) connected to the CO2 board that will then power the micro:bit (but not both). * Connections - alligator/crocodile leads are notorious for failing while looking perfectly ok. Try swapping the leads ...

CO2 Sensor SKU:SEN0159 - Digi-Key

can divide it by the module's gain, that is in the example2. if you got , then ZERO_POINT_VOLTAGE = / = NOTE: It is not a good idea to use a Voltage Meter on pin 1 and pin 2 on the back of the sensor. It seems working, but actually, since CO2 sensor has a large built-in resistance, generic voltage metre
