Design of Rural Age-Friendly Smart Seat Based on Arduino

Abstract

With the accelerated aging of China’s population, the aging problem in rural areas is particularly prominent, and current rural public facilities lack age-friendly design and intelligent services. To address this issue, this paper proposes a design scheme for a rural age-friendly smart seat based on the Arduino Uno R3 platform. The system combines ergonomic theory in structural design, optimizes seat height, depth, and armrest structure, uses pressure sensors to detect sitting posture, employs temperature and humidity sensors for environmental monitoring, and integrates an OLED display and buzzer to implement prolonged sitting reminders. Interfaces for sit-to-stand assistance and voice interaction are also reserved. The paper analyzes the usage needs of the rural elderly, constructs the system architecture, completes hardware and software logic design, and demonstrates the technical feasibility of core functions such as sitting detection, prolonged sitting reminders, and environmental monitoring. Research shows that the system can stably achieve sitting state recognition and timed reminder functions, with controllable monitoring errors, low power consumption, and simple structure. While ensuring basic intelligent functions, the design reduces system complexity and cost, making it suitable for rural public spaces and home-based elderly care. This study provides a feasible approach for the intelligent design of rural age-friendly public facilities.
