Heart rate measurement is a basic and essential for daily health monitoring. A heart rate monitoring system is a personal monitoring device that allows one to measure heart rate in real-time. If someone wants to record the data or use it to trigger events, there is a need to turn that mechanical pulsing action into an electrical signal and this can be done only through heart rate measuring system. The pulse rate helps to find out if the heart is pumping enough blood to the body and also helps to find the cause of various symptoms such as an irregular or rapid heartbeat, dizziness, fainting, chest pain or difficulty in breathing. More than million people are at high risk of having heart related diseases. It would be helpful if there was a way for these people to check the heart rate by sitting at home. In this paper focus have been made on realizing a portable, comfortable and low cost solution for long-term domestic heart rate monitoring. There are various methods or technologies to measure the domestic heart rate. We have mainly focused on IoT-based, polymer-based pressure sensors, optical sensors, plastic optical fiber sensor, smart phones, MEMS based piezoelectric pressure sensor. The most effective method will be considered as an efficient way of detecting the heart rate.
