Since 1980, numerous perilous and transmissible diseases have emerged and continue to persist. These diseases pose significant challenges globally, affecting both developed and developing nations with limited resources. Consequently, they have garnered considerable attention in the twenty-first century, primarily due to their economic and health impacts. Halting the emergence of new infectious diseases presents a formidable task, given the interconnectedness between individuals, animals, and the environment. Nevertheless, it is possible to implement precautionary and preventive measures, such as comprehensive global surveillance and advancements in diagnostic technology, active treatments, and vaccines. By examining specific diseases as examples, we can highlight human activities that contribute to the transmission and development of infectious diseases. The COVID pandemic serves as a stark reminder, with over 20 million reported infections and a staggering death toll of more than 730,000 globally. Monitoring the health-related characteristics of affected patients remains a daunting challenge, primarily due to limited resources and the risk of contagion. Direct contact between doctors and patients is often impossible. In this project, a novel Internet of Things (IoT)-based health monitoring system is proposed. Utilizing the ThingSpeak cloud application, doctors can remotely monitor patients' body temperature, heart rate, and pulse rate. Additionally, the system can issue emergency alerts through Telegram. The work introduces a new paradigm for telehealth monitoring systems, centering around the ESP32 development board equipped with active sensors such as the DHT11 and MAX30100. This system continuously monitors patient-specific health parameters, wirelessly transmits the data to an IoT server via WiFi, and enables real-time data analysis on the ThingSpeak cloud. Given that this chronic virus significantly affects vital health indicators like body temperature, pulse ...
