Heart related issues have been so common according to medical research; the young and aged people are mostly affected. Electronic diagnosis has made a great impact in solving Heart related issues. However, the cost for acquiring stethoscope and Electrocardiographs is often expensive This simple, low cost microcontroller based heartbeat rate measuring device was developed using a reverse engineering technique. A five volts power supply (5V) was developed and used to power a sensor arrangement. The sensor comprised of an Infrared emitting diode and a photodiode. An amplifier unit was added to boost the signal coming from the sensor after which the signal was sent to a microcontroller. The microcontroller was programmed to count detected pulse for fifteen seconds and give the display through a connected 3-Digit seven segments. The device was packaged in a specially designed plastic casing; adequate spacing was provided for the digital readout, optical sensor, power switch and the control switches. Testing was done by using the device to measure the heartbeat rate of 42 individuals and the result compared with that of a standard device. The result using the developed device was found to be satisfactory as 73.69bpm average measurement while the polar sonic standard device gave an average reading 74.23bpm. A positive strong correlation of 0.907 was obtained for the two devices showing that the developed device is a good substitute for the (polar sonic) standard device. The device is simple in construction, easy to use, portable and cost effective.
