How to make a Cat Repellent with a Motion Sensor

Does your cat jump on the table and you don't know how to wean him? In this video I will show you how to make diy a cat repellent with a motion sensor that shoots water.
I made the basis for the DIY craft from cardboard. I glued a long thread bolt to the 12V motor. I glued the nut to the syringe. It turns out that when the engine turns in one direction or the other, the syringe piston will move forward or backward, collecting water or spraying it.
I connected the motion sensor to the relay module and connected two switches so that one would turn on the motion sensor itself, when triggered, water would be sprayed, and the second switch I connected so that when turned on, the engine rotated in the other direction to draw water into the syringe.
I connected the homemade motion sensor to a 5V battery, and the motor to a 12V battery.
I glued a small cardboard tube to the motion sensor to narrow down its field of action.
And now an amazing cardboard craft was ready. Now, when a cat or any animal passes the motion sensor, the motor will start and a syringe will spray water into the pet. Don't worry, no pets will be hurt) The water pressure is not strong.
This is a cool cat repeller with a motion sensor! With it, you can wean the cat from jumping on the table :)
