Noninvasive pulse measurement and wireless iransmission

Today, the rapid development in technology has given way to many innovative research activities in the field of health. In particular, wireless communication systems are increasingly used in medical device applications. Long-term or real-time monitoring of medical data and informing of relevant institutions in critical situations have become indispensable with the aging and growing population. At the same time, the patients at the hospital are cured, but the patients who need to be supervised at home need to be checked by the experts of all kinds of current health data. In this study, it was aimed to calculate pulse rate by taking a PPG (Photoplethysmography) signal on body simultaneously via a microcontroller. This calculated heart rate was sent to the mobile phone using Bluetooth wireless technology. With the developed mobile application, it is possible to send the pulse value of the phone to the desired persons via SMS. This makes it possible for the health situation to be monitored outside the hospital while the person performs daily activities.
