/**
 * @brief Class for sensors that convert from some raw floating point
 * value (ex: voltage, frequency, pulse width) to a sensor reading.
 *
 * To use this class, implement the conversion operation for your sensor
 * as a class that inherits from SensorConverter, and implement convert
 * to convert a raw reading from the sensor to a usable value (and valid bit).
 *
 * Register an instance of the new class with an interface
 * that provides and posts raw values so the sensor can update.
