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 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.
Recent years have seen an increasing demand for portable devices featuring greater energy savings and miniaturization. Among wearables such as sports bands and smart watches heart rate monitoring capability has become mainstream with new functions continually being added. However, their limited battery capacity makes it necessary to reduce power consumption as much as possible to prolong operating time.
