The focus of this project is to implement an intelligent health care system based on internet of things (IOT) for the measurement of the vital signs like pulse rate, temperature, spo2, using (ESP32 div kit) for wireless wearable sensor controller and ESP32 server. With the system proposed, the doctor can save work time to visit the patients that responsible about them and any facilitates monitoring the huge number of patients. The WI-FI technology is utilized as a communication tool to allow transmission the data remotely. The data of patient are sent to the web server to be stored in the database and view the data on the web page anywhere and anytime using smart devices and alert the doctor to any abnormal state. This work with the intelligent health care system provide an efficient medical service, by collecting and recording the information that include heart rate, temperature and spo2 that enable the doctor to monitor this patient with flexibility and confidence. Also, we highlight the challenges in the implementation of IoT health monitoring system in real world.
