Designing 3 language talkative system of heart beater

Today, the increasing contribution of biomedical devices is well known for diagnosis and treatment of common diseases. The heart rate is an important parameter among this diagnosis. The heart rate is the total number performed heart beats in a minute. In this study, the heart rate is detected proportionally to the intensity oxyhemoglobin inside the finger. Oxygen is greatly carried with the hemoglobin units in the blood. When oxygen-rich blood reaches the finger tissues, the absorption against light of the tissue will change. To detect this difference, finger is illuminated with the help of a red LED and to detect this information a probe is designed with the help of a fotoresistor. A system design have been made announcing the heart rate obtained from the designed probe in three different languages.
