<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;">温湿度传感器使用STM32G030K6T6为主控,盛思睿SHT40温湿度传感器用于检测温湿度,将检测后的数据显示在三位数码管上。因为考虑到功耗问题,本项目使用两节5号电池进行供电,电压在3V左右,默认不开机,进入睡眠模式,通过按键来触发中断来唤醒芯片进行工作,将获取的温湿度显示在数码管上;唤醒后会启动定时器中断,循环显示温度和湿度两次后会再次进入睡眠,等待下次唤醒。由于此项目是低功耗的,两节5号电池能够待机很久。</p>

<p><span style="color: #95a5a6; font-size: 14px;"> PCB采用两层设计,需要注意的是SHT40传感器在布局中需要原理发热元器件,避免发出的热量影响传感器的检测。</span></p>

<p>焊接方面使用的都是0603封装的阻容,比较号焊接,焊接芯片推荐使用刀头电烙铁和0.5的焊锡,先将顶层的元器件尤其是数码管焊好后再焊接底层的电池座。需要注意的是本项目中使用的SHT40传感器是非常小的贴片芯片,需要使用加热台和锡膏。</p>
