【 摘 要 】

For high precision and low cost, the heart rate monitor system by using NodeMcu was invented which can be used in several applications such as patient treatment and monitoring in places away from the center of cities for the initial diagnosis purpose, elderly health care or sport training. in this paper a new system for detecting and remote monitoring cardio-vascular pulse wave was invented which depends on the NodeMcu board which is built-in a Wi-Fi module with an easy pulse sensor. In this proposed system the easy pulse sensor which has been used for detecting of heart rate and send it to NodeMcu board which transmits such data to the intended destination using the internet. The basic work of heartbeat Sensor used in this design depends on the principle of photo plethysmography to obtain vital information of the heartbeat from the skin surface. the calculation of heart beat was done using two methods, first by tracking the peaks in the PPG waveform while the second way by calculate the frequency of the digital output wave form which is simultaneous to the heart rate pulse. The preliminary result show that the new system is more reliable and lower cost compare with other system based on IOT Microcontroller and gives good and optimum results.
