Good day to all! In today's article, I would like to tell you about a very interesting and useful product from the Aliexpress website, this product substitutes a system of as many as sixteen independent relays attached to the control and wiring board. This "big relay" was created for the Arduino microcontroller and created for a very wide range of projects. But as for me, this module is simply ideal for creating a smart home system, as you probably know Arduino is ideal for simple projects on the topic of "smart home", but since almost all lighting and other electrical appliances in the house are powered by 220 volt AC then you have to use a mechanical relay that can withstand this voltage. Using arduino and relays, for example, you can automatically turn the light on and off (let us go from sound or any third-party signals), control the power of the kettle, table lamps, radio, TV and so on. As you understand the scope of application is huge.
This relay is able to withstand a current of 10A.
As you understand, the product is quite useful and interesting, by the way it costs not very much.
Well, thank you all for your attention and good luck in future projects, friends!
