基于FireBeetle 2 ESP32-C6的迷你气象监测仪 DF创客社区

   FireBeetle 2 ESP32-C6是一款基于ESP32-C6芯片设计的低功耗物联网开发板，搭载了CN3165锂电池充电管理芯片，配合太阳能板可实现不间断供电功能。还支持电池电压检测，可实时了解电池剩余电量。
   此次测试是用FireBeetle 2 ESP32-C6制作了一个可以持续供电的迷你气象站。显示模块使用了一块2.0" 320x240 IPS广视角TFT显示屏，传感器使用了五合一环境传感器这是一个集成了SHTC3温湿度传感器、BMP280大气压强传感器、VEML7700光照传感器、紫外线传感器共五种环境参数的五合一传感器。每一种环境参数都使用了专业传感器芯片，电路设计上也精心考虑了核芯片的合理布局和热传导，有效的保证了数据的准确性。产品板载了MCU处理芯片，将传感器的原始数据经过换算，得到的值就是标准单位值。
   首先测试了充电功能，将太阳能板的正极焊接在ESP32-C6的VIN串口，将负极焊接在ESP32-C6的GND串口。接一个3.7V锂电池到ESP32-C主板，完成后上代码在屏幕显示环境数据和锂电池电量查看效果，在室内阳光不是很充足的情况下居然可以正常充电。

程序测试很顺利，剩下的就是结构部分了。由于最近很忙就不用3D打印和激光雕刻了，家里还有点乐高件就简单搭建了一下。
