Network Controlled Relay Switches [Copy link]

Hello seniors, I want to make a control circuit to control the level of TTL by sending codes through the network. I checked some information and it seems to be made by using a network control switch. I am not very clear about the internal circuit structure of this network switch. I would like to ask the seniors how to make such a network control switch circuit by myself

I don't quite understand what you mean. If you want to remotely control the level, just use the network module.

I use a voltage regulator to generate a TTL control level, and use a switch to control the output of 5V or 0v. I have to use the code transmitted over the network to control the on and off of the switch.

The question is too general. What communication protocol is used? Is it controlled by a mobile phone or a computer? If you design this kind of circuit yourself, the knowledge involved is relatively broad. If you just want to find such an application, you can search for such network control switches on Taobao.

Electronic switches to control output are nothing more than transistors or MOS tubes. There are many such switch circuits, and they are also easy to implement. But as the above said, don't talk about it in too general terms, maybe everyone has misunderstood it.

Only when the requirements are clearly described can the appropriate solution be selected

The attachment is for reference only. The USR-C215 module hardware integrates MAC, baseband chip, RF transceiver unit, and power amplifier; the built-in low-power operation mechanism can effectively realize the low-power operation of the module; it supports WiFi protocol and TCP/IP protocol. Users only need simple configuration to realize the networking function of UART devices. In simple terms, the coded instructions you send are converted into signals that can be received by the communication module (e.g. USR-C215) according to a specific network communication protocol, and then sent to the microcontroller. The microcontroller controls your switch to control the output, and then in turn detects the output signal through the microcontroller A/D port, returns to the network communication module, and finally displays the output status on your terminal. Specifically, it is too complicated, so study it slowly.
