【Training Camp】wifi smart switch +387925A

# Overview #

Use the Tuya smart module to control an IO port to switch the relay on and off, and display the current status of the relay through the indicator light. This project can remotely switch on and off electrical equipment. For example, it can be used for remote control of computers. It can be powered on and started in the computer BIOS settings. The computer installs a self-starting remote software to achieve the purpose of remote switching on and off.

Features

1. High security. The design adopts a variety of protections, such as: terminal insulation top cover protection, PCB slotting to prevent creepage, fast-blow fuses, strong and weak current layout separation, insulating shell sealing protection, etc.
2. easy to use. Just connect to the AC220V you want to control, no external power supply is required. There is only one physical button in the whole. This button only needs to be pressed and held for the first time to configure the network. It can also be used as a manual short press control relay. The board is equipped with 3 color indicator lights. The blue light is the network indicator light. It flashes when the network is configured and stays on when connected to wifi. The red light is the power indicator light, which can effectively determine whether the smart switch is working. The green light is the switch indicator light. When the relay is closed, the green light is always on, and when the relay is disconnected, the green light is off.
3. Superior performance. This smart switch can effectively attract, carry, and disconnect mains power up to AC220V16A, fully meeting the load of ordinary household appliances. The WiFi module's anti-interference and signal strength have been verified by long-term operation.
