Iot based smart health monitoring system

People who require constant monitoring, which cannot be offered outside of hospitals, would benefit from smart healthcare. It's especially crucial in rural areas like villages, where neighbourhood clinics can communicate with city hospitals regarding their patients' health. This project shows a smart health monitoring system that employs biological sensors to monitor a patient's condition and the internet to notify those who need to know. The biomedical sensors are attached to an Arduino UNO controller, which reads the data and displays the results on an LCD display/serial monitor. The data is uploaded to the server, where it is stored and translated into a JSON link that can be seen on a smartphone. An Android application has been created to allow doctors and family members to conveniently view the patient's information. Heart attack has become a particularly fatal human disease in recent years. This assault cannot be predicted, but it can be detected by monitoring the human heartbeat, which is a critical health indicator for the cardiovascular system. Heart rate represents the state of health of the human circulatory system, which is influenced by factors such as stress at work, physical exertion before or after sports, and psychological factors. Unfortunately, some persons are unaware of their heart rate prior to or after engaging in a physical activity.
