Human Physiological Condition Monitoring System based on Microcontrollers

With the rise in living standards, people are increasingly focusing on their health, and monitoring their physiological condition has become a popular trend. Sudden illnesses or hidden chronic conditions can cause abnormal fluctuations in temperature and heart rate, which can be difficult to detect without continuous monitoring. The main objective of this project is to develop a cost-effective and efficient system to monitor vital signs such as heart rate, body temperature, and steps taken, based on systematic experimental studies. The system utilizes a pulse sensor DS18B20, and ADXL345 to monitor the heart rate, body temperature, and motion status of the human body. The circuit and the HC-05 work together to transmit the detected data from the sensor to the MCU, which further transmits it to the LCD1602 or mobile phone interface for real-time display. The system provides a user-friendly interface and real-time monitoring, making it easier for individuals to keep track of their health status. This paper presents an innovative approach to human physiological condition monitoring using a microcontroller-based system, which has significant potential for improving healthcare by enabling early detection and prevention of medical conditions, ultimately leading to better quality of life.
