The principle of smart switch socket
This article mainly introduces The principle of smart switch socket.
The simple understanding of wifi smart switch socket is to add a serial port WIFI module to our home wall switch. The socket to realize the conversion of serial data to wireless data. On the mobile phone, we will also configure a simple application app operating platform (app Some are developed by hardware companies themselves. Also some are directly used by third-party intelligent platforms). In this app, we configure the corresponding switch sockets and application scenarios according to the operation instructions. That as to realize the direct control of the switch through the mobile phone.
In addition to the above-mentioned protocol modules, the wifi smart 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 and process various input signals and form the output.
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, and the output is mainly a relay.
Through the above comparison, we can see that the wifi smart switch socket is more complicated than the traditional wall switch, uses more electronic materials, and some control ICs or modules are expensive. So its cost is quite high. Of course, this may also relate to the level of R&D engineers. But no matter how much you save materials, some major electronic components still have to be used. You can’t get them without dozens of dollars.
