ALAT MENGHITUNG BPM DENGAN MENGGUNAKAN FINGER SENSOR BERBASIS MIKROKONTROLLER AT89S51

Abstract

In the world of medicine has been around electrocardiograph (ECG) which serves to show the human heartbeat signals. Thus, in the development of technology electrocardiograph (ECG) is rapidly increasing, the disease patients do not need to use electrodes that attach to the position of the human heart. To replace the electrode is used an infrared transmitter and receive rphotodioda. Where the placement of sensors on the fingertips, to get the heart rate is in because of the operation that reflects infrared light onto the surface of the finger and will receive the infrared light from the photodioda.
From the resulting data is then processed using the photodiode signal conditioner, it can produce a good heart rate data. Furthermore, heart rate data are calculated in a period of time (minutes), then the resulting haert rate in units of beats per minute (bpm).
It is hoped that these tools can help medical experts in analyzing the condition of the patient's heart with the ease of installation of the sensors and heart rate that appears
