文章简介:	基于STM32的水质检测系统设计

一、题目要求

说明：（溶解氧浓度的硬件太贵就没做这个）
功能如下：
1.通过TFT屏实现实时各数据，可进行多级菜单切换
2.可以通过按键进行温度、PH、采集频率调节
3.可以通过语音控制温度、PH、采集频率的调节（SU-03T语音模块）
4.通过ESP8266将采取的数据上传到Onenet云端
5.采取的数据超过设置阈值会进行报警提示
6.大气压采取BMP180模块

成品展示

二、硬件材料

$NG6{J5GIRT8S~SZ_C9OH4KV.png$

STM32F103C9T6最小系统

SU-03T语音模块

PH传感器模块（这个相对来说比较贵60几吧）

ESP8266模块

TDS传感器

BMP180大气压传感器

DS18B20温度传感器

TFT显示屏

蜂鸣器

三、部分代码
