[Training Camp_Advanced Class] IoT switch based on 51 microcontroller +570333W

Overview

The IoT switch

master control based on 51 microcontroller is 51 microcontroller. It should be considered the best 51 microcontroller at present, but it is still a little behind STM32.

The IoT module uses the EMW3080 module. The specific use requires guidance from the teacher:)

The relay circuit passes 51 The microcontroller sends a 0 signal to the relay terminal and completes the 5V coil to close the 220V contact.

Updated on August 17. Add a diode to the communication line between the CH340C and the microcontroller to prevent current backflow;

reorganized the power supply part of the CH340C and corrected the error part;

August On the 20th, the code for the device AP distribution network was corrected;

on August 21st, I felt that welding was a bit difficult, and 5 scrap boards were produced. . . .

Prepare to re-sample. . .

Signal gain and noise gain of op amp
The concept of noise gain is rarely used in our daily designs, because it is usually not that important, and ignoring it will not have much impact on our design, so we rarely consider it. But sometime
