+/** BH1790GLC class
+ *
+ *  BH1790GLC: an I2C bus optical sensor for heart rate monitor library
+ *
+ *  BH1790GLC is optical sensor for heart rate monitor IC in
+ *  which LED driver and green light detection photo-diode
+ *  are incorporated. This device drives LED and provides
+ *  the intensity of light reflected from body.
+ *
+ *  For more information about BH1790GLC:
