Development of smart electronic system with high performance, large adoptability and portability, to sense the biomedical parameters is highly needed for medical instrumentation. Recently, in the biomedical field, there has been a growing demand for high-tech instrumentation to monitor various parameters such as temperature, blood pressure, heartbeat, and blood sugar, among others. Out of various parameter heart beat monitoring system plays significant role in daily life. Considering the need, an embedded system design based on advanced microcontroller for heartbeat measurement and presented in this paper. Heartbeat Sensor is an electronic device used to measure the heart rate, which refers to the speed of the heartbeat. Monitoring body temperature, heart rate, and blood pressure are fundamental practices for maintaining good health. The required firmware developed in Arduino IDE to show pulse count. The system is implemented for monitoring heartbeat of different age group person and obtained results discussed in this paper.
