AbstractWith the rapid development of modern animal husbandry, traditional pigfarming relies too much on manual labor, which is not only inefficient, but alsodifficult to ensure the stability of the breeding environment and animal welfare.To address these issues, this design has developed a pig feeding monitoringsystem based on the STM32 microcontroller.This design uses the STM32 microcontroller as the core component fordevelopment, and the infrared proximity sensor is used to detect the approach ofanimals to trigger the feeding program. The DS1302 clock module is responsiblefor timing control to ensure the regularity of feeding. Using weighing sensors toaccurately measure the amount of food, ensuring that each pig can receive anappropriate amount of feed. Use a stepper motor to control the opening andclosing of the feeding valve, achieving precise feeding. Using DHT11 sensors tomonitor and regulate environmental temperature and humidity, maintainingsuitable feeding conditions through

毕业设计（论文） 课题名称基于 STM32 的生猪养殖系统设计与实现学 院电子信息学院专 业电子信息工程学生姓名代鑫学 号189120243指导教师陈德伟职 称副教授2022 年 5 月 20 日重庆工程学院本科生毕业设计（论文）摘要I摘 要随着我国对猪肉的需求日益增大，因此，要求生猪养殖业的生产方式由传统养殖向综合化、规模化发展，生猪的生长环境对生猪的健康影响越来越大。根据用户的实际应用，设计了一种基于 STM32 生猪养殖系统的产品设计方案，主要由数据采集器和自动控制两部分组成。数据采集器主要用来负责采集到的空气中的温度、二氧化碳浓度和湿度以及氨气浓度，再通过 STM32 单片机自动控制猪舍环境质量，也可以让饲养人手动按键操作对猪就行喂食和猪舍消毒。本设计的主要设计内容：(1)数据采集器的硬件、软件设计方法。在硬件上设计上，STM32 单片机作为核心控制器；(2)STM32 通过采集的数据自动对猪舍环境就行调控。本文设计的生猪养殖系统具有功能齐全、可靠性高、稳定性好、安装维护方便等特点。它不仅可以实现生猪养殖环境的信息采集和空气控制，还可以适应猪舍各种环境数据的多样化管理管理。关键词：猪舍环境；STM32 单片机；自动监控；消毒重庆工程学院本科生毕业设计（论文）ABSTRACTIIABSTRACTWith the increasing demand for pork in China, the production mode of pig breeding industry is required to develop from traditional breeding to comprehensive and large-scale development, and the growing environment of pigs has an increasing impact on the health of pigs.According to the actual application of users, a product design scheme based on STM32 pig breeding system is designed, which mainly consists of two parts: data collector and
