Wildlife Frightener / Infrasonics Wild Animal Fright

Wildlife Frightener
Wildlife Frightener

It has been reported frequently these days that wild animals attack the farmhouses because of the lack of their food.

In order to prevent the damage, I designed [Infrasonics Wild Animal Frightener].

This device detects the invasion of wild animals using infrared sensor(lower than 18Hz) and protects people from their attack by radiating infrasonics which tigers make.

Even though this infrasonics are inaudible to human beings, animals get frightened and nervous when hearing this range of sound and run away.

Also, this is environmental-friendly because it's powered by solar panels so you don't have to use extended wires.
