Design and Implementation of a Human Physiological Parameter Collection System

With the continuous development of technology, the collection of human physiological parameters has become increasingly important in the medical and health industries. Thus, we propose a human physiological parameter acquisition system based on a microcontroller and the Internet of Things (IoT). This system is based on the AT89C51 microcontroller as the core, combined with Bluetooth modules, temperature sensors, pulse sensors, blood pressure sensors, and other devices. It enables real-time collection and wireless transmission of physiological parameters of body temperature, pulse, and blood pressure. Digital temperature sensors are used for temperature collection, while pulse oximetry sensors and blood pressure sensors are used for pulse wave and blood pressure collection. Bluetooth modules are used for wireless data transmission, solving the drawbacks of wired transmission. A user interface allows users to switch between different physiological parameter display interfaces through buttons and view their physiological parameter data in real-time. At the same time, the system has a recognition function, which collects user information through identity card scanning and facial recognition, ensuring the accuracy and security of data.
