The principle of wifi smart switch socket
The simple understanding of the smart WIFI switch is to add a serial WIFI module to our home wall switch socket to realize the conversion of serial data to wireless data. We will also configure a simple application app operating platform on the mobile phone. In the app, we configure the corresponding switch socket and application scene according to the operation instructions. So as to realize the direct control of the switch through the mobile phone.

The smart wifi switch socket also contains at least the following modules:
1 Power processing part, that is to convert AC power into DC power required by various signals or control modules
2 The signal control part, similar to the CPU of the computer, has already burned the program chip in the smart switch socket to receive .
3 Input signal part, that is, various input signals, there may be wifi signal, touch signal, key signal, etc.
4 The output signal part is used to control the operation of electrical appliances, and is generally composed of relays or thyristors.
In our traditional home wall switch. It is mainly composed of input signal and output signal, and the input is mainly a button switch.
Through the above comparison, we can see that the smart wifi switch is more complicated than the traditional wall switch, uses more electronic materials. So some control ICs or modules are expensive, so its cost is quite high, of course. This may also be related to the level of R&D engineers. But no matter how much you save materials, some main electronic components still have to be used. And you can’t get them without dozens of dollars.
