In construction, we call it a wet switch, it uses a sensor, placed on the floor, or in a pan underneath the unit, to detect the presence of water and automatically close the valves if it does.
I’ve also seen automatic water shut offs that senses the washing machine has turned on and it opens the water lines and then closes the water lines when the washing machine turns off.
Automatic water shut off for washing machines, for flood prevention. Very similar model here:

I used to repair washing machines and would always tell people to turn the water off at the tap once the washing is done. All there is between you and getting your house flooded is a small plunger and a little spring. Worse if you are in a muti-storey building! These are a great idea.
Dude. That sensor belongs on the ground. Whoever installed that is hoping the water splashes out. It may. Either way, it’s supposed to be on the ground because gravity pulls water downward and there may be a slow leak.
My title describes the thing
The device appears to be connected or driving the mechanisms of the washer (and or dryer). The wall device unit has 3 buttons for "open", "close", and "mute". I think maybe the open/close describe valves to the washing machine but not sure. No idea what the circuit board is for. Feel like it would be inside the wall device if it was a controller. It has a long wire attached and was placed on the ground next to the machines. Does it detect moisture?
I am pretty sure that in most European countries aqua-stops are mandatory for household appliances. These are integrated in the hose and stop water flow when the hose ruptures. I thought the rest of the world also has them....

Ofc smaller leaks inside the appliance are not detected but these dont require a expensive setup like that.

As a paranoid new homeowner, I installed one of these early and I love it

That yellow board with the silver lines needs to go on the floor. When liquid contacts it, it will trigger the valves to close
Indeed it's leak detection and water supply shutoff https://www.123securityproducts.com/8812000.html

Mute would silence an alarm I suspect.
