【Training Camp_Advanced Class】Internet of Things Socket

Overview

This design is an IoT switch based on 51 master control and Alibaba Cloud server.
In the power design, the power supply of WIFI and MCU are separated to ensure that the communication module has a stable power supply, and the connected VCC is stepped down to 3.3V through LDO.
The burning program circuit adopts the typical circuit USB to TTL, and is built with CH340E chip and microUSB.
The WIFI module uses EMW3080, a highly reliable commercial WIFI module, which has been officially tested after access to Alibaba Cloud.
The MCU uses STC MCU. Since the function of this design is relatively simple, only a few peripherals are used.
The relay module is driven by 220V, so pay attention to strong electricity when using it.
Connect DSI8B20 temperature sensor, LED light and button to expand some functions and facilitate debugging.
