A wireless health care product became popular in our life. Although continual detection is crucial for health care devices, most of the products are not convenient to wear for a long time due to their size, battery life, cost, etc. To cover such defections, I developed Photoplethysmography using optical proximity sensors to detect heart rate.







The strong points of this sensor are small size and low-battery consumption. Therefore, the sensor can be installed many places such as ring, eye-glasses, watch, etc.User can check the real-time heart-rate data with smartphone. And the stored data in the memory chip will be helpful when they visit a hospital to track their health history.
