Abstract
Smart phones today have turned out to be progressively well known with the people for its different capacities like Social Media, Gaming and many other facilities to name a couple. These smartphones are furnished with top of the line processors, high definition cameras, worked in sensors like accelerometer, direction sensor, light-sensor, and considerably more. The motive of the project Health monitoring using smart phone sensors is to use these extensively used smartphones for bio-medical applications. In recent times heart related issues has become more prominent for the man kind and need to monitor heart rate and breath rate more frequently. Even though many equipment’s with less cost are available to monitor these vital signs, people are in need of something unique that they could use by their own anytime needed. So, the application to monitor these vital signs such as breath rate and heart rate is created. The application uses camera to measure the pulse rate, microphone and speaker to detect breath rate, and accelerometer sensor to get the vibrations of the heart rate. By using pulse rate and vibrations captured using accelerometer, blood pressure can be calculated. The pulse rate calculation basically relies on capturing the time between opening of the aortic value and pulse reach to peripheral arterial site. And breath rate calculation depends on peak values obtained in the acoustic wave form which is captured using the microphone. The application is helpful for the people who want to check their vital signs wherever they want and also during unexpected situations like fainting or minor crash incidents.
