1、设计要求
本毕业设计以单片机作为控制核心芯片，设计出一款具有监测鱼缸水的温度、水位、浊度和PH值等参数，并且通过WIFI模块连接云平台用来实现数据上传和下发，
2、系统功能
（1）基于STM32F103C8T6为主控制器的智能鱼缸的设计与实现。其中包括基于STM32F103C8T6单片机的最小系统的搭建，温度传感器、浑浊度传感器、水位传感器等相关器件模块的选型和原理图设计，在上述原理图的基础上搭建硬件平台并验证其功能的完善性。
（1）ESP8266-01Wifi模块。通过本模块单片机系统可以连接到机智云，手机APP就可以远程控制鱼缸的开关。
（2）水位传感器器。水位传感器用来检测鱼缸内的水位，是鱼缸的水位保持在一定的范围内，通过比较水位和水位的阈值来控制补水泵和排水泵。
（3）温度传感器，温度传感器用来检测鱼缸内的水温，使鱼缸保持恒温。
（4）PH传感器，用来检测鱼缸内的PH值。
（5）水泵继电器模块，用继电器来驱动两个水泵。
（6）时钟模块。利用时钟振荡电路产生时钟信号。单片机时钟可以提供一个固定的时钟频率，用于同步和控制各个模块的操作。通过时钟信号的控制，可以确保单片机系统中各个模块按照一定的时间序列进行操作，从而实现定时功能。
（7）OLED显示模块。OLED显示模块采用0.96寸液晶显示屏，该模块用来实时显示传感器数据及鱼缸工作状态
（8）按键模块。按键模块用来控制模式选择和控制鱼缸的开启与关闭。
（9）蜂鸣器模块。设备出现故障用来报警。
（10）舵机用来控制净水系统的开关。
