BH1790GLC-E2

ROHM Semiconductor BH1790GLC-E2 Optical Heart Rate Sensor is a photodiode designed to measure pulse waves, which are changes in the volume of a blood vessel that occur when the heart pumps blood. Pulse waves are detected by measuring the change in volume using an optical sensor and green LED. The BH1790GLC-E2 Optical Sensor features an optical filter optimized for pulse wave detection. This filter minimizes the effects of ambient light and increases the sensitivity and accuracy of the sensor block.

ROHM announces the availability of an optical sensor for heart rate monitoring optimized for wearable devices such as sports bands and smart watches. The BH1790GLC-E2 leverages proprietary analog circuit technology and optical sensor expertise to improve sensitivity, allowing pulse waves to be detected with high accuracy, even with low LED brightness, resulting in class-leading low power consumption.
