基于STM32F103RB的模拟液位检测告警系统（已实现）

这次先看一下老朋友STM32，有关Zigbee的内容（Z-stack协议栈和基于Zigbee的环境温湿度+烟雾传感器的环境监测系统），等有时间再更。基于STM32的模拟液位检测告警系统，记得好像是某一届蓝桥杯省赛题~~

基于STM32告警系统介绍

“模拟液位检测告警系统”通过采集模拟电压信号计算液位高度，并根据用户设定的液位阈值执行报警动作,在液位等级发生变化时,通过串行通讯接口将液位信息发送到PC机。系统框图如下图所示:

下面是我的代码，我都标了注释。

ok，上面是我在main.c文件里的全部代码，蓝桥的板子下载没用FLYMCU或是ARM仿真器，有专门的CooCox下载，下面看一下实验现象~
1.液位检测

2.液位阈值设定

3.液位阈值设定

4、串口查询与输出功能

5．状态指示

emmm…有时间的我会更新和补充其他届的省赛赛题，希望能对大家有所帮助~~
