Optical Sensor for Heart Rate Monitor - BH1790GLC

BH1790GLC is optical sensor for heart rate monitor 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. LED brightness can be adjusted by LED driver current and light emitting period. The photodiode having the high sensitivity for green light, excellent wavelength selectivity and excellent lrcut characteristics achieves accurate pulse wave detection.
