BH1790GLC
BH1790GLC is Optical Sensor manufactured by ROHM.
Sensor for Heart Rate Monitor ICs
Optical Sensor for Heart Rate Monitor IC
General Description 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. 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.
