Floating Elves / waterlogging warning

Floating Elves
Floating Elves

When the flood occurs, a product called "Floating Elves" can effectively alert people to avoid deep-water areas, especially the low-lying sections of the city, using the principle of water pressure triggering and laser devices to protect the lives and property safety.
It is a public utility product that alerts people to avoid deep water, when the external water pressure reaches a certain value.The thin film at the bottom will be triggered and connect the circuit to emit a laser. Meanwhile, as there is gas space inside the product, it will float on the water immediately after triggering. This product can be applied to the inside of speed bumps
