基于stm32的宠物饲养远程控制系统设计 -视频分享
二、项目简介
题目：基于stm32的宠物饲养远程控制系统设计
主控:STM32
显示:OLED显示屏
温湿度:dht11
红外光电检测余量
光敏电阻检测光照强度
控制模块:一个加水继电器 一个投喂步进电机
水位传感器检测水位
usb小灯
esp8266透传控制单片机并且接收数据
功能：
1、可分为手动和自动模式，可通过手机或者按键修改 自动模式下，检测水位是否过低，过低会打开加水继电器模拟加水，光电检测实物余量 过低自动打开步进电机进行加食物，根据换光照强度自动选择开灯或者关灯。
2、屏幕实时显示温湿度，水位，食物余量。投喂次数，当前模式。
三、原理图设计
四、PCB硬件设计
五、程序设计
