描述
<p><h3 style="line-height: 1.8;"><em> 1、项目功能介绍</h3>
<hr />
<p style="line-height: 1.8;">本项目通过STM32和盛思锐传感器而制作成的具有较高精度的温湿度检测仪;可以通过通用的Type-C 5V或两节五号电池进行供电,同时具有休眠功能,并且通过按键进行唤醒,从而进行实时温湿度检测的功能。</p>
<h3 style="line-height: 1.8;"></em>2、项目属性</h3>
<p style="line-height: 1.8;">该项目是通过首次公开自行设计电路布局和增加了type-c供电功能并成功完成实物验证的工程。</p>
<h3 style="line-height: 1.8;"><em> 3、开源协议</h3>
<p>GPL3.0</p>
<h3 style="line-height: 1.8;"></em>4、硬件部分</h3>
<p style="line-height: 1.8;">该项目通过5号电池或usb-c转3.3V进行供电,通过STM32G030K6T6这颗单片机和三颗三态输出八位移位寄存器以及盛思锐传感器模块为主的桌面温湿度传感器。<br />下面是5V转3.3V模块</p>

<p style="line-height: 1.8;">下面为电路走线设计,采用了常规双层板设计</p>
<p style="line-height: 1.8;"><img src="//image.lceda.cn/oshwhub/d3656a7f18d3460f84735b46fe84932f.png" alt="" width="465" height="546" /><img src="//image.lceda.cn/oshwhub/7f05a3dfef1144cda3bf09d6e1ca1e4d.png" alt="" width="476" height="549" /></p>
<p style="line-height: 1.8;">下面是黑油沉金的电路板样式</p>

<p style="line-height: 1.8;">焊接建议:先从最大的STM32开始焊,之后再焊三颗寄存器,再焊接type-C母座,最后焊其他元件,type-C母座针脚极细要极其注意,很容易就焊坏了,不焊也不影响使用,只是少了使用手机充电器供电的功能,板子较大,焊接相对难度还行。</p>

<p style="line-height: 1.8;">采用5V type-C供电时整体休眠待机功耗约为0.029W左右,整体测试时功耗约为0.155W左右(使用FNB58S进行测量)。</p>
<h3 style="line-height: 1.8;"><em>5、软件部分</h3>
<p style="line-height: 1.8;">使用cubemax和keil5软件进行编程,通过pwlink进行下载即可实现功能,即首先激活芯片,然后获取传感器数据,再通过寄存器输出至二极管显示当前的温度和湿度。</p>
