BH1792GLC
Optical Sensor for Heart Rate Monitor

BH1792GLC is optical sensor for heart rate monitor IC in which LED driver, green light and IR detection photodiode are incorporated. This device drives LED and provides the intensity of light reflected from body. LED brightness can be adjusted by LED driver current. The photodiode having the high sensitivity for green light and excellent wavelength selectivity achieves accurate pulse wave detection.
