基于合宙Air700E的4G环境监测节点（温湿度、气压等数据） - 嘉立创EDA开源硬件平台

基于合宙Air700E的4G环境监测节点（温度、湿度、气压等数据），通过MQTT上传阿里云物联网平台。 ## 介绍 合宙Air700E 4G模块读取传感器（温度、湿度、气压等）数据并通过MQTT协议上传阿里云物联网平台，数据也会同时显示在0.96寸的OLED屏幕上，使用了U8g2图形库。 ESP32C3 WiFi模块通过MQTT协议订阅4G节点上传的数据并显示在LCD屏上，使用了LVGL图形库。 这是我的一个课程设计，随便做做的，不是很完善。 > **题目要求**：设计并制作无线通信系统，结合上学期所学知识，将本地采集的温、湿度/超声波测量距离通过无线收发的方式，发送到主机/接收端，并在接收端利用 LCD显示相关信息，具体要求如下： > > ⑴ 蓝牙无线传输系统设计实现 > > ⑵ WiFi 无线传输系统设计及实现 > > ⑶ ZigBee 无线传输系统设计及实现 > > ⑷ GPRS/GSM 无线传输系统设计及实现 > > (5) 4G 无线传输系统设计及实现 > > (6) NBIoT/LoRa 无线传输系统设计及实现 > > **提示**：可用 8/16/32 处理器作为主控制器，按照本小组选定的综合部分内容来进行选型，至少完成 2 个小项，其中（1）（2）（3）选 1 个完成，（4）（5）（6）选 1 个完成。 Air700E和ESP32C3我都是使用LuatOS系统+Lua脚本的开发方式来开发的。 LuatOS固件是我使用合宙的云编译生成的。 ESP32C3上自带的4MByte的flash被我换成了8MByte的了，固件也是大于4MB的，因为加了LVGL图形库以及几种字体。 **阿里云学生优惠地址：**[https://www.aliyun.com/daily-act/ecs/activity_share?userCode=jdjc69nf](https://www.aliyun.com/daily-act/ecs/activity_share?userCode=jdjc69nf) **注意：** 由于阿里云物联网平台不同设备间不能订阅对方的主题，只能订阅本设备的主题，所以需要在 **消息转发→云产品流转** 那里添加一条规则，将4G节点设备的发布的消息转发到WiFi节点设备的一个主题。 ##
