Smart System for Real-Time Remote Patient Monitoring Based on Internet of Things

Patient monitoring has become one of the most popular studies and is of interest to many researchers worldwide due to the development and growth of healthcare technologies. People in rural areas face multiple diseases and issues due to distance, lack of doctors, and lack of medical treatment for patients. One of the best solutions to these issues is remote patient monitoring. This paper proposes a real-time remote patient monitoring system based on the Internet of Things that can monitor the basic vital signs of the patient, such as body temperature, heartbeat rate, and blood pressure. The core of the system is a wearable device consisting of a microcontroller, a Wi-Fi module, and sensors. Sensors are used to capture patient's vital signs, and the data captured by the sensors is transmitted to the cloud database via a Wi-Fi module. The doctor can real-time monitor the patient via an Android-based smartphone application or retrieve previously recorded data via a website. Moreover, the system will send a notification to the doctor application if any of the vital signs exceed the predefined threshold value. Thus, the real-time remote patient monitoring system helps in the early detection of critical condition and contributes to saving people's lives.
