pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;">此项目采用主控为<span style="color: #3598db;">STM32G030K8T6</span>。STM32G030K6T6也可以直接替换，官方使用的就是此款芯片。采用<span style="color: #3598db;">tp4056</span>芯片给锂电池进行充电。温湿度传感器芯片选用金主&nbsp;<strong><a href="https://list.szlcsc.com/brand/506.html" target="_blank" rel="noopener">Sensirion(瑞士盛思锐)</a></strong>&nbsp;的高精度数字温湿度传感器芯片&nbsp;<strong><a href="https://item.szlcsc.com/3188621.html" target="_blank" rel="noopener">SHT40-AD1B-R2。</a>电路简单，容易上手。</strong></p> <p

pap-spacing-after-3pt" style="line-height: 1.8;">由于一开始画错了pcb，现在<strong>已修改</strong>，<strong>已验证</strong>。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto

pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;">上电后，屏幕就显示温湿度，3s更新一次。这块屏幕用起来很耗电，采用墨水屏显示可能会好很多。所以我取消了睡眠功能。</p> <p class="paragraph

pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;">拨动开关可以选择更小的，不然电池不太好放。这里我选择的是m2X8铜柱 和m2x3+m2X8螺丝。如果不更改，可以选择更高的铜柱。</p> <p class="paragraph
