Sensirion SCD30 CO2, humidity and temperature sensor

Sensirion’s SCD30 sensor module ( is a useful device for environmental monitoring. I’ve wrapped a modified version of SparkFun’s Arduino Library (



Nice job Matt! That was quick…Jim

Cool! Is there a way to transfer a library for MH-Z19 CO2 sensor?

Sorry it has taken me a while to reply. There are a couple of class-based arduino libraries for this sensor:

If you have experience with C++ you could try wrapping one of the above libraries - see

Alternatively, since the sensor communicates via serial, it may be possible to implement everything you need in xod using the UART nodes ( Commands can be found in the sensor’s datasheet:
