To measure the Heart beat rate we can simply hold ones wrist and measure but, it is not that practical. Other way is to use a heart rate monitor, but they are quite expensive.

This project was brought to us by a Bio Medical enthusiast, and he wanted to go an extra mile with this project. The sensor used in this project is a Hearbeat sensor which is compatible with Arduino. Heart beat sensor is available in may of the devices that we use in our day to day activities such as wrist watch, smart phone, chest strap and etc. Heart beat sensor consist of two parts as shown in the figure below, This sensor have ...
