Portable ECG Monitoring Device Design Based on ARDUINO

Biomedical signals are the primary data source for diagnosis of diseases and monitoring of patients. These kinds of operations are carried out in hospital environment with huge devices. Today, due to rapid development of embedded systems, sizes of these devices have been reduced to small dimensions. In this way, while the patients continue their daily lives, the small sized devices make it easier to record biomedical signs related to their diseases. In this study, the electrocardiogram (ECG) sign, one of the most basic signs for heart diseases, is detected and displayed on the graphic display. To determined for this goal, ECG sensor card, wireless communication module, ARDUINO nano and TFT LCD screen are used. The idea is designed independently in two circuits and all circuits are supplied with small batteries for compact size. In this way, the circuits are realized in small sizes. According to the results, the system proposed can detect heart signals and heart beats and the system can show results to users.
