Wearable wireless sensor network and ECG design

The design and development of wearable wireless sensors, improving the quality of life for health monitoring has garnered lots of attention during the last years. This technology helps the chronically ill and elderly to survive an independent life. One of the most common and important chronic diseases is heart disease, it is the main topic of this thesis. In this thesis work in the wireless ECG signals in the health system is widely used in the diagnosis of chronic heart disease. ECG signals detected by the sensor from the patient's body is transferred to a computer desktop wirelessly. These signals are digitized using a 5 V voltage range, with the help of LDR sensor and Arduino Nano CH340G microcontroller. Arduino microcontroller is programmed in own programming language (close to C language) and on own application. Arduino Bluetooth module as the wireless communication HC-06 is used. To display ECG signals that are transmitted to a computer, I created an application using Visual Studio and C # language program.
