Human Physiological Condition Monitoring System based on Microcontrollers

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