基于STM32和Linux的远程智控项目

项目要求

SHT20检测温湿度, 将温湿度的数值上传到OLCD屏
当湿度高于设置阈值, 控制风扇排风
当湿度低于设置阈值, 控制马达震动模拟加湿过程
通过按键,可以修改阈值(阈值信息在OLCD显示)
STM32 与 ESP8266 基于 TCP通信
实现TCP服务器(Linux端)控制加湿器, 当STM32接收到:
FAN_ON, 控制风扇旋转
FAN_OFF,控制风扇停止
MOTOR_ON, 控制马达震动
MOTOR_OFF,停止马达震动
HUM:(阈值), TCP服务器修改湿度阈值
TUM:(阈值), TCP服务器修改湿度阈值
STM32 每隔2s 将SHT20数据上传到 TCP服务器(Linux端), Linux端可以将SHT20数据上传的Sqlite数据库中
STM32可以向ESP8266发送指令 "CLEAR" : 清除TCP服务器SQLITE数据库中的数据
