<h3 style="line-height: 1.8;">1、项目属性及功能介绍</h3>
<hr>
<p style="line-height: 1.8;">小白基于2024立创暑期训练营复刻的温湿度计。</p>
<p style="line-height: 1.8;"><strong>MCU</strong>采用<strong>STM32G030K6T6,温湿度传感器</strong>采用<strong>Sensirion(瑞士盛思锐)SHT40温湿度传感器模块,</strong>可实现高精度的温湿度检测,并有低功耗运行模式,以节约用电。</p>
<p style="line-height: 1.8;"> </p>
<h3 style="line-height: 1.8;">2、开源协议</h3>
<hr>
<p>GPL 3.0</p>
<p> </p>
<h3 style="line-height: 1.8;">3、硬件部分</h3>
<hr>
<p style="line-height: 1.8;"><strong>3.1、原理图</strong></p>
<p style="line-height: 1.8;"><strong><img style="display: block; margin-left: auto; margin-right: auto;" src="//image.lceda.cn/oshwhub/ff109cf856ca456cb7e369d7c26d6185.png" alt="" width="1199" height="365"></strong></p>
<p style="line-height: 1.8;"><strong>MCU</strong>采用<strong>STM32G030K6T6</strong>,Arm Cortex-M0+内核,最大主频64Mhz、Flash32K、SRAM8k,供电电压在2.0V~3.6V。</p>
<p style="line-height: 1.8;">没有主晶振,pin2、3作为OSCIN、OUT连接外部32.768kHz低速无源晶振。</p>
<p style="line-height: 1.8;">磁珠用于隔离滤波高频干扰。</p>
<p style="line-height: 1.8;"><img style="display: block; margin-left: auto; margin-right: auto;" src="//image.lceda.cn/oshwhub/f27804ea8c41479b8b3286c21898bdf7.png" alt="" width="609" height="439"></p>
<p style="line-height: 1.8;">温湿度传感器使用<strong>Sensirion(瑞士盛思锐)SHT40温湿度传感器模块。</strong></p>
<p style="line-height: 1.8;">pin1、32开漏输出,外接4.7KΩ上拉电阻以输出高电平。</p>
<p style="line-height: 1.8;"><strong>3.2、PCB</strong></p>
<p style="line-height: 1.8;"><strong><img src="//image.lceda.cn/oshwhub/1a006e4f385549fdab6439611498d0f7.png" alt=""></strong></p>
<p style="line-height: 1.8;"><strong><img src="//image.lceda.cn/oshwhub/1214d5903bd740e8a089bcfb95c969d7.png" alt="" width="771" height="539"></strong></p>
<p style="line-height: 1.8;">数码管横向设计,处显示温湿度外,还便于显示时分秒时间。</p>
<p style="line-height: 1.8;">卧插传感器模块正面向下,否则3V和GND将短接。</p>
<h3 style="line-height: 1.8;"> 4、软件部分</h3>
<hr>
<p style="line-height: 1.8;">采用STM32CubeMX软件进行基础代码生成与配置,Keil uVision5调试。</p>
