Following series adds support for Sensirion SCD30 sensor module capable of measuring carbon dioxide, temperature and relative humidity. CO2 measurements base on NDIR principle while temperature and relative humidity are measured by the on board SHT31. As for sensor communication, both I2C and serial interfaces are supported.
