BIOMETRIC BASED HEART RATE AND TEMPERATURE MONITORING


Inspite of the improvement of communication link and despite all progress in advanced communication technologies, there are still very few functioning commercial wireless monitoring systems. In this project we are going to develop an embedded system to sense the heart beat and temperature. Biometrics is the science and technology of measuring and analyzing biological data. In information technology, biometrics refers to technologies that measure and analyze human body characteristics, such as fingerprints, eye retina’s and irises, voice patterns and for authentication purposes.
Using a heart rate and temperature monitor we can keep track of the heart functionality and body temperature. Heart rate monitors can measure the cardiovascular and physiological stress and temperature. They provide you with an accurate gauge of the intensity of an exercise, which is reflected in your heart rate. The harder you exercise, the higher the heart rate and temperature should go.
During various exercises, it circulates the blood from the lungs to the trunk and lower extremities. Monitoring the heart rate is the easiest way to keep the body working in the right zone, to reduce the chance of injury and overtraining of the heart.During the measurement, the heart rate pulse and temperature will be sensed by corresponding sensors and the sensed data will be sent to the microcontroller. On receiving the pulse rate and body temperature, the microcontroller will display it on the LCD display connected to it.
