Heartbeat Sensor is an electronic device that is used to measure the heart rate i.e. speed of the heartbeat. Monitoring body temperature, heart rate and blood pressure are the basic things that we do in order to keep us healthy
This device is recommended for use at homes and for
individual use. However, because of its less precision and
accuracy, individuals should not rely solely on the measured
values. Therefore, more research is needed in order to
improve its accuracy and hence making it usable in the
clinical world
