// The core of the implementation for this device library is in the SparkFun Toolkit object sfDevSoilMoisture,
// contained in the directory sfTk. This object implements all functionality independent of the bus type, I2C or SPI.
// The SparkFunSoilMoistureSensorI2C and SparkFunSoilMoistureSensorSPI classes below are the Arduino-specific,
// bus-specific implementations that inherit from the core toolkit class.
