一、设计背景和意义

1.1设计背景

在现代农业快速发展的背景下，智能化养殖已成为推动农业产业升级的重要方向之一。传统养殖方式普遍存在人工管理强度大、实时性差、环境控制滞后等疑问，特殊是在温湿度、光照、水质、空气质量等关键环境因素无法实现精确调控的情况下，极易导致动物应激、饲料浪费、疫病传播等风险，从而制约了养殖效益的提升与规模化发展。当前市场上虽然存在部分商用的智能养殖解决方案，但往往存在价格高昂、系统封闭、部署复杂、定制性差等问题，难以被广大中小型养殖户广泛接受。同时，这类产品在灵活性和可扩展性方面也存在一定局限性，难以根据具体的养殖需求进行灵活配置。

1.2设计意义

传统养殖业中，人工巡检存在效率低下、误差较大且难以实现 24 小时连续监测的问题，这往往导致环境异常不能被及时发现，进而影响养殖生物的生长甚至存活。而该体系能够实时、精准地监测养殖环境中的温湿度、空气质量、光照强度等多参数，一旦发现异常便能迅速响应，有效减少环境变化对养殖生物的不良影响，显著提高养殖生物的存活率。不仅如此，远程控制与自动调节功能的实现，大幅降低了人工干预的成本，让养殖管理不再受地域和时间的限制，极大提升了养殖管理的智能化水平。

【开源】基于STM32的智能养殖环境监测系统

三、硬件功能简介

3.1项目功能详解

传感器检测：检测温湿度、氨气浓度、饲料重量、水槽水位、光照强度等数据。
数据表明：0.96OLED屏幕显示全部的传感器内容以及传感器的阈值等素材。
执行机构：控制风扇、水泵、LED灯、步进电机（喂食）。
接入云平台：系统通过ESP8266 WIFI联网后，接入机智云平台。
App远程监控：通过App远程监控全部传感器数据；App远程控制LED和步进电机。
通过阈值信息设定：系统通过按键设定阈值，也能够通过手机App远程设定。
模式切换：可能通过按键或者手机App搭建自动/手动模式的切换。
手动模式：凭借手机App或小程序控制开关
自动模式：检测到光照强度低于阈值，自动打开补光灯；检测到水位低于阈值，自动打开水泵；检测到氨气浓度或温度超过阈值，打开风扇通风，并蜂鸣器报警；检测到饲料重量低于阈值，自动打开步进电机喂食。
