style="color:#000000;font-size:24px;">前言: </span></h2> <div class="document"> <div class="section"><hr class="horizontal-splitline normal"></div> </div> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">最近天气比较热,经常开空调不通风。由于长时间封闭房间内不通风会导致空气的二氧化碳比例上升。时间久了会犯困打瞌睡,导致工作效率降低。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">我们每时每刻都在呼吸,一个人每天要大约要呼吸两万多次,每天至少要与环境交换一万多升气体,可见空气质量的好坏与人的健康息息相关。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">以上,我诞生了一个制作了一款便携桌面空气质量监测仪的想法。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">该便携桌面空气质量监测仪不仅实现了对空气中<span style="color:#000000;font-size:14px;"><span style="color:#000000;" xml:lang="zh">CO<sub>2</sub></span></span>的读取,还顺便实现了监测温湿度、TVOC、空气PM浓度、及空气悬浮颗粒物计数以及数据定时上报等功能。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto

<p>想打一个pcb,这个是几层板子啊</p>
sakura_shiling 回复
<p>双层板,建议把自己把温湿度传感器用FPC排线接出来测量(板子发热影响),否则可能测不准</p>
dhdhhd 回复
<p>请问工程压缩包里,是包含了每个工程吗?</p>
sakura_shiling 回复
<p>是打包的项目代码哦</p>

<p>请问下是要把图上这个排针插座焊接到pcb上用来连接pms7003吗</p><p><img src="//image.lceda.cn/pullimage/jH398OLivXhGYHsTyyOg3fX6IOf8d4QTTb8F2O9r.webp" alt="jH398OLivXhGYHsTyyOg3fX6IOf8d4QTTb8F2O9r.webp"></p>
sakura_shiling 回复
<p>某宝搜1.27mm 2*5P 双排母,是用贴片的</p>
rier 回复
<p>非常感谢!我正纳闷怎么焊这东西呢</p>
dhdhhd 回复
<p>这款检测仪能通过蓝牙用手机端查看信息吗?</p>
sakura_shiling 回复
<p>等我有时间把工程更新了(咕咕咕)</p>
rier 回复
<p>请问下锂电池接口的母座正极是图中的方孔还是圆孔呀,顺便问下锂电池尺寸大小有啥要求嘛</p>
sakura_shiling 回复
<p>我买的是403040电池(3.7V/XH2.54反向插,方孔是正极),然后电池是放在屏幕下边,esp-01S可以反过来焊排针,插背面(!注意引脚对应关系!)</p>
sakura_shiling 回复
<p>esp-01S焊了排针过后,把排针自带的塑料拆了,引脚剪短一点,然后主板的位置焊个排母,可以随时拔下来接烧录器更新固件</p>
rier 回复
<p>收到!</p>
rier 回复
<p>请问下有烧录教学嘛,新手开着文件夹不知道该怎么办,或者告知下bin文件用哪个加上烧录地址?</p>
sakura_shiling 回复
<p>keil5打开工程编译,下载。使用下载器SWD下载方式直接下载就行</p>
rier 回复
<p>收到谢谢大佬</p>
zzzzzzz2q 回复
<p>作者你好,请问后续的ESP-01S上报参数有更新计划吗!</p>
sd-xo-xo 回复
<p>虽然我几年2024年刚刚看到,还没开始复刻,但是看到这儿,你这个开源的项目是见过最好的,没有之一,不管成功与否必须给予前辈的尊重!!。感谢前辈的努力付出!</p>
