Development of an Electronic Bird Repellent System using Sound Emission

Currently, the damages caused by the stalking of birds in industry and agriculture are of great consideration, because they adapt to city environments in search of food and lose their fear, creating threats and taking advantage of the human presence, benefiting from food and waste, causing diseases and great economic losses. Therefore, the objective of this paper is to design a repellent system that allows birds to keep away from the facilities of companies and homes. There are various methods to repel birds using traditional and technological methods, such as the use of temperature or distance sensors, microcontrollers, and sirens. Therefore, this paper describes the development of the device to keep birds away. The design of the printed circuit board, implementation of the control algorithm for the system, the evaluation of the system through simulation, and the design and development of the casing for its integration are shown. Finally, a functional prototype of the repelling device is shown, to detect the presence of the bird and immediately emit a sound that scares it away, using the algorithm integrated with the electronic system.
