Heart rate measurement is one of the chief significant parameters of the human cardiovascular system. The heart rate of a strong adult at rest is about 72 beats per minute (bpm). Athletes typically have lower heart rates than less active people. Babies have a much larger heart rate at around 120 bpm, while older kids have heart rates at around 90 bpm. The heart rate increases progressively during exercises and proceeds deliberately to the rest value after exercise. The rate when the pulse proceeds to usual is a warning of the fitness of the person. Lower than usual heart rates are frequently an indication of a condition known as bradycardia, while advanced than normal heart rates are referred as tachycardia. More sophisticated approaches to evaluate the heart rate employ electronic techniques. Electro-cardiogram (ECG) is one of commonly employed and precise approaches for gauging the heart rate. ECG is an exclusive expedient and its usage for the measurement of the heart rate only is not cost-effective. Low-cost devices in the form of wrist watches are also existing for the instant measurement of the heart rate. Such strategies can offer precise measurements but their charge is frequently in superfluous of several hundred dollars, creating them inefficient. Most hospitals and clinics in the UK use unified devices intended to measure the heart rate, blood pressure and temperature of the theme. Although such devices are beneficial, their cost is frequently great and beyond the reach of people. This short editorial note defines the design strategy of a very low-cost device which processes the heart rate of the subject by clipping sensors on one of the fingers and then exhibiting the result on a text based LCD. The expedient has the benefit that it is microcontroller based and thus could be programmed to parade numerous quantities such as the average, maximum and minimum rates over a period of time and so on.
