Patients are confronting numerous issues because of the particular explanation of heart issues and assault due to nonexistence of good clinical upkeep to patients when they required. This is designed for monitoring the old patients and passing information to doctors and also loved ones. So by this innovative project we can reduce death rates by using Patient Health Monitoring that uses sensor technology and also internet connectivity to communicate with the loved ones in case of emergency. This system uses Temperature, heartbeat sensor, saline level indicator and accelerometer to track patient’s health. Both the sensors are associated with the Arduino-UNO. So as to follow the patient wellbeing condition a miniature regulator is interfaced to a LCD show and Wi-Fi regulator to send the information to the web-worker (remote detecting hub). In case of any sudden changes in patient heart-rate or body temperature alert is sent about the patient using IOT. This system also shows patients heartbeat, temperature, saline level and acceleration tracked live data with timestamps over the Internetwork. Thus Patient health monitoring system based on IOT uses internet to effectively monitor patient health and helps the user monitoring their loved ones and saves lives. Key Words: IOT, LCD Display, Wi-Fi controller, server. 1. INTRODUCTION Lately, remote innovation has expanded for the need of maintaining different divisions. As of late, IOT got a handle on most mechanical territories particularly mechanization and control. Biomedical is one of the ongoing patterns to give better medical care. In medical clinics as well as the individual wellbeing caring offices are opened by IOT innovation. So having shrewd framework different boundaries are seen that expends force, cost, and increment effectiveness. As indicated by this brilliant framework, this paper is explored. In conventional strategies, specialists assume a significant part in wellbeing registration. For this cycle requires a great deal of time for enrollment, arrangement and afterward registration. Likewise, reports are produced later. Because of this extensive cycle working individuals will in general disregard the exams or defer it. This cutting edge approach diminishes time utilization simultaneously. Medical scientists are trying in the field of innovation and research for many decades to get better health services and happiness in human lives. The body temperature, heart rate, saline level, acceleration are prime parameters to monitor. This project gives temperature and heart rate values using IOT. 2. EXISTING SYSTEM In a hospital, either the doctor or nurse has to move physically from one person to another for checking health condition, which may not be possible to monitor their health conditions continuously. Thus, any critical situations are not found easily unless the doctor or nurse checks the person’s health at that moment. This may be a strain for the doctors who have to take care of many numbers of people in the hospital. Also, when medical emergencies happen to the patient, they are often unconscious and unable to indicate or press an Emergency Alert Button. More than 50% of hospital deaths occur in patients who are not continuously monitored. 3. PROPOSED SYSTEM In this proposed Patient monitoring system we use NodeMCU, two Arduino’s and the respective sensors. These sensors used to monitor the different parameters of an ICU patient remotely and also control over medicine dosage is provided. This system enables doctors to monitor vital parameters like body temperature, heart rate, acceleration and saline level of patients in remote areas of hospital as well as he can monitor the patient when he is out of the premises. If the parameters goes to abnormal these system sends alert Popup message to the doctors or it makes a buzzer sound. All these information and communication between doctor and patient is possible only through the website. NodeMCU is worked as server which takes the information gathered by Arduino’s from sensors and puts complete information on the website created. This system gives the minute to minute update to the doctor. Thus, we can reduce the deaths and can save people more easily. A.
