将MCU上集成的传感器值通过串口传输到阿里云服务器上，同时也可以通过上位机下发指令控制MCU上开关通断(The sensor values integrated on the MCU are transmitted to the Ali cloud server through the serial port. At the same time, the switch on the MCU can be controlled through the upper computer to contr

使用stm32f103平台，通过485 modbus协议对传感器数据进行采集，并通过EDP协议上传至云平台。(Using the STM32F103 platform, the sensor data is collected through the 485 Modbus protocol and uploaded to the cloud platform through the EDP protocol.)
