Study of a Low-cost Heart rate Remote monitoring system using the Arduino platform
Currently, remote monitoring systems have evolvedto respond to the peculiar needs in the healthcare industry, suchas Cardiovascular diseases, which is an essential foundation in themodern concept of the smart city. We propose a system to monitorpatient current health conditions as a healthcare system basedon the widely spread available low-cost technologies, namely,GSM and Arduino platform. Statistics show that hypertensiveheart disease and blood pressure are risk factors for the highdeath rate. To decrease it, preventive measures should be appliedproviding a health monitoring system to save the patient life atan acceptable time. The objective of this paper is to developa prototype of a low-cost system, that is capable of performingremote monitoring of a patient’s heart rate and body temperaturein real-time and stores the data on the memory card using low-cost hardware such as Arduino, and also, using the servicesprovided by the GSM network, to enable communication witha health specialists cell phone upon request or if there areanomalies in the values measured by the sensors. The studyfocuses on heartbeat rate using the Difference Operation Method(DOM), described by Yeh & Wang, and body temperature, thus,in case of emergency, a short call is done, and then an SMS issent to the health specialist’s mobile containing measured values.Using this algorithm and after some tests using data from theMIT BIH Database distribution, we manage to find the bestsample frequency and eliminate the distortion of the signal.sample frequency and eliminate the distortion of the signal.
