Hello friends, how are you? Today I have made a circuit that will work automatically. Just by raising any object or hand in front of it, the water will automatically turn on.
It is very easy to make, you will only need these few things - IR sensor and relay module and 3.7 V battery and mini water pump and switch and plastic pipe .
And if you want to buy electrical items online, you can buy them by clicking on the image below the video.
And friends, this is a past school project.
