* 1、项目功能介绍
本次工程主要是做桌面迷你温湿度数显器，其主控采用STM32G030K6T6芯片低功耗设计按键触发，传感器使用盛思锐优秀传感器进行数据采集，用数码管来显示，可以实时采集环境温湿度，测量温度在-5——105度，湿度在0-90度范围内，精度高，体积小，功耗极低等特点。
*2、项目属性
原创模仿
* 3、开源协议
完成自己的第一次画电路板，写程序，完成软件的配置和实物的调试工作。
产品具有低功耗和数显功能，其他我在以后的使用过程中进行升级改造。
程序使用中断延时等功能。
*4、硬件部分
产品成品3D图如下图：
原理图如下图：体会是绘制原理图比较简单，原件摆放和走线考验经验和规则。
PCB走线图如下图
*5、软件部分
