Traditional trash bins rely on manual opening/closing and manual judgment of fullness, with problems such as cumbersome operation and delayed cleaning, making them difficult to meet the hygiene needs of modern homes.​The intelligent trash bin design based on the STM32F103C8T6 microcontroller integrates HX711 weighing module, DS18B20 temperature sensor, infrared obstacle avoidance sensor, SG90 servo, ULN2003 stepper motor driver module, OLED display, buttons, and ECB02 Bluetooth module, realizing automatic management and intelligent control of the trash bin. The core functions of the system include: detecting whether there is a person in front through the infrared obstacle avoidance sensor, and controlling the SG90 servo to drive the bin lid to open automatically when a person is detected; monitoring the weight of garbage through the HX711 module, triggering sound and light alarm when exceeding the set maximum weight, and simulating automatic packing through the ULN2003-driven stepper motor; detecting the internal temperature via DS18B20 to assist in judging garbage spoilage; supporting weight threshold setting through buttons; displaying real-time weight on the OLED screen; transmitting weight and temperature data to the mobile phone via the Bluetooth module, enabling remote monitoring and control of packing, opening, and closing.​The implementation of this system effectively improves the automation and intelligence level of trash bins, reduces manual operations, realizes timely garbage disposal, provides a hygienic and convenient solution for smart home life, and also offers a reference for the research and development of similar intelligent sanitation equipment, with high practical application value.Keywords:STM32F103C8T6; Intelligent trash bin; Weight monitoring; Automatic packing; Sensor; Bluetooth communication目录第1章 绪论1.1 研究的目的及意义1.2 国内外发展情况1.3 本文主要研究内容第2章 设计思路与方案论证2.1 主要元器件选择2.1.1 主控芯片选择2.1.2 称重模块选择2.1.3 温度传感器选择2.1.4 红外避障传感器选择2.1.5 舵机选择2.1.6 步进电机及驱动模块选择2.1.7 显示模块选择2.1.8 蓝牙模块选择2.1.9 按键模块选择2.2整体设计方案第 3 章 硬件设计3.1 主控电路模块3.2 称重模块电路3.3 温度传感器电路3.4 红外避障传感器电路3.5 舵机驱动电路3.6 步进电机驱动电路3.7 显示模块电路3.8 蓝牙模块电路3.9 按键模块电路3.10 声光报警电路第4章 系统程序设计4.1 编程软件介绍4.2 系统主流程设计4.3 独立按键4.4 温度检测模块子流程设计4.5 OLED显示流程设计4.6 步进电机子流程4.7 舵机子流程设计4.8 称重模块子流程设计4.9 红外避障模块子流程设计4.10 蓝牙模块子流程4.11 声光报警模块子流程设计第 5 章 实物测试5.1 整体实物测试5.2 称重模块功能测试5.3 温度传感器功能测试5.4 红外避障传感器功能测试5.5 执行设备功能测试5.6 按键与显示功能测试5.7 蓝牙模块功能测试5.8 声光报警功能测试第6章 总结与展望6.1 总结6.2 展望致谢参考文献附录附录一原理图附录二PCB附录三主程序
