There are three sets of lights in the home that form the background lighting system, and three switches and one socket form a four-position 118 switch combination.
It was changed to PT2262 remote control more than ten years ago, and now it is changed to mobile phone remote control. In fact, there is nothing new.
The difficulty is that the entire system needs to be placed into a three-position 118 back box (the socket positions remain unchanged). The board size is 7.6*4*2cm, and the structure is compact, but the safe creepage distance is ensured.
There are 3.3V and 5V power supplies respectively, complete safety and anti-interference measures, 470uf large capacitor and special supervision chip to make the system run smoothly.
At the same time, Tuya has smart high-power devices that can set many schedules to turn lights on and off every day or every week.
We were short of time and only made a development-free system. However, I took this opportunity to make a successful IoT product for the first time, which made people more confident. The company's products are also planning to join the IoT. The next step is to implement various Everything is connected! hehe.
