Esp32-c3 single fire wire intelligent switch enables intelligent upgrading of traditional switch

Traditional mechanical switch , Spring pieces made of copper alloy and silver alloy contacts are used , The mechanical combination and disconnection can be realized by manually operating the seesaw structure or swing rod structure , To turn on or off the light .

Compared with traditional mechanical switches, intelligent switches , The biggest difference is that the electronic circuit is used to open and close instead of the mechanical combination and disconnection .

Its core component is the power supply module 、 Wireless modules and relays , The wireless module receives the remote control 、 mobile phone APP、 Instructions from smart speakers, etc , And transmit the control command to the relay , Perform on and off operations .

ESP32-C3 wireless Wi-Fi Single live wire intelligent switch , It can not only effectively solve the problems of high power consumption and complex installation of equipment , It can also ensure its Wi-Fi Through wall performance and secure data transmission , Enable traditional switches to quickly realize intelligent upgrading .

Smart switches significantly improve the convenience of home control , It also helps to be more efficient 、 Use electrical appliances in an energy-saving way , Therefore, it has been welcomed and recognized by consumers , Quickly popularized in home decoration .

however , The smart switch must always be live , To ensure that control instructions are received at any time . Therefore, in terms of wiring mode , It is essentially different from the traditional mechanical switch , That's what happened “ Zero fire ”、“ Single fire ” Two wiring modes .

The wiring of the mechanical switch is very simple , There are only two wires , A hot wire , A load line . So here comes the question , If a mechanical switch is replaced by a smart switch , There is only live wire on the switch , There is no zero line , How to supply power ？

“ Zero fire version ” Wiring mode intelligent switch , An additional zero line is required to supply power to the power supply module of the intelligent switch , To ensure that the power supply module can supply power to the wireless module at any time , In order to receive the signal .

It seems that the problem has been solved , But the disadvantages of this kind of intelligent switch wiring are also very significant ： The switch base shall be reserved during installation 1 Root FireWire and 1 Zero line .

This is not a big problem for newly decorated houses , But in the renovation of old houses 、 When replacing an ordinary switch with a smart switch , Will face the embarrassment of the lack of zero line , In general, such scenes , Large area re wiring is also unrealistic .

Intelligent switch “ Single fire ”( Two wire system ) Wiring mode , Single fire switch , seeing the name of a thing one thinks of its function , There is only one live wire on the input side , At the output side, the load control line is connected with the lamp , The neutral line is connected to the other side of the lamp .

In order to form a complete power supply circuit , The current to the intelligent switch enters from the live wire , Through the load control line , After lamp load , From the zero line . There is no need to change the line for the installation of single fire switch , Compatibility is good. , New and old houses can be installed , More widely used scenarios .

ESP32-C3 Industry leading RF performance ,Wi-Fi RF receiver (RX) Sensitivity can be as high as –98.4 dbm,Wi-Fi RF transmitter (TX) The power can be up to 21 dBm, Even if the equipment is installed in the wall, it can remain smooth 、 The stability of the Wi-Fi Connect .

be based on ESP32-C3 Of Wi-Fi Single live wire intelligent switch scheme , Users do not need to change the line 、 There is no need to configure the gateway , The traditional mechanical single fire switch can be upgraded to an intelligent single fire switch , Low build power consumption 、Wi-Fi Performance is remarkable 、 Safe and reliable intelligent switch .

ESP32-C3 The chip adopts advanced power management technology and superior performance Wi-Fi Processing strategy , Keep the switchgear on hold Wi-Fi The connection also has ultra-low power consumption , Meet the needs of most lighting scenes .

Because the intelligent switch needs to be embedded in the wall during installation , Therefore, the equipment Wi-Fi The anti-interference ability through the wall also needs to reach a higher standard .

Two pieces ESP32-C3 Chip usage Wi-Fi When communicating , The farthest communication distance in open environment can reach 500 m, You can still reach... When crossing three walls 20m, Fully meet the communication needs of daily home scenes .
