Shoo Heron!

Outsmart a clever bird

Shoo Heron!

The idea is to protect the pond with an invisible barrier that is connected to a powerful water spray. Herons dislike being sprayed and will leave. Furthermore, they can’t easily determine what causes the spray to start.
The protection consists of an infrared transmitter and receiver that are mounted close to each other.

Gerber file

CAM/CAD data for the PCB referred to in this article is available as a Gerber file. Elektor GREEN and GOLD members can exclusively download these files for free as part of their membership. Gerber files allow a PCB to be produced on an appropriate device available locally, or through an online PCB manufacturing service.

Elektor recommends its business partner Eurocircuits as the company of choice for its own prototypes and volume production in selected cases.
