* @brief C++ API for Grove light sensor * @brief C++ API for Grove light sensor

* Very basic UPM module for Grove light sensor on analog * The Grove light sensor detects the intensity of the ambient light.
* As the light intensity of the environment increases, the resistance
* of the sensor decreases. This means that the raw value from the
* analog pin will be larger in bright light and smaller in the dark.
* An approximate lux value can also be returned.
