There have been several attempts to use the new technology in various fields to improve the quality of life as a result of technological advancement and the shrinking of sensors. Since the last ten years, the healthcare monitoring system has evolved into one of the most important systems and has become more technologically focused. Unexpected deaths from a variety of ailments are an issue that affects people, and it is caused by a lack of timely medical attention for patients. The main objective is to create an IoT-based patient surveillance system that would assist healthcare providers in keeping track of their patients. An IoT-based integrated healthcare system can monitor this both in hospitals and at patients' homes to provide improved patient care. Medical professionals or caregivers can remotely access patient data to monitor health improvements from locations outside the hospital. The application of Internet of Things (IoT) principles has been widespread in connecting available medical resources, offering patients intelligent, reliable, and efficient healthcare. This project has introduced a specially designed IoT architecture tailored for healthcare applications. Therefore, the suggested design gathers the sensor data using an Arduino microcontroller and transmits it to the cloud where it is processed and examined before being displayed. In the event of an emergency, patients' actions based on the health data analysis can be sent back to the doctor or nurses via messaging.
