基于51单片机的绿植多肉养殖系统温度光照监测遮阳proteus仿真原理图PCB

功能介绍：
0.本系统采用STC89C52作为单片机
1.系统实时监测当前的光照和温湿度
2.支持手动/自动两种模式
3.自动模式下，当光强超过阈值或温度超过阈值时，关闭遮阳伞，起到遮阳降温的作用
若光强和温度值适宜，但湿度较高，打开遮阳伞，让环境通风
4.按键可设定阈值，手动控制遮阳伞，切换工作模式
5.WIFI定时发送监测的光照和温湿度
6.WIFI可控制电机，切换工作模式。
*C# 关闭遮阳伞 *O# 打开遮阳伞 *M# 手动模式 *A# 自动模式
7.采用DC002作为电源接口可直接输入5V给整个系统供电
