Intelligent Assistant for Elderly Traveling Based on Internet of Things and Sensor Technology

This study proposes an intelligent travel assistance system for the elderly based on the Internet of Things (IoT), which realizes real-time monitoring and intelligent response to the living environment and health condition of the elderly through multi-sensor fusion and wireless communication technology, and improves the safety of the elderly travel. The system takes STM32F103C8T6 controller as the core, integrates environment monitoring module, health monitoring module, identity recognition module, etc., adopts ESP8266 module and MQTT protocol to realize data transmission in the cloud, and displays real-time monitoring information and personalized service with the help of WeChat applet. At the same time, the system is designed with a hierarchical warning mechanism to ensure that family members can be notified in a timely manner in case of emergencies, to improve the efficiency of emergency response and to protect the travel safety of the elderly.
