Design of elephant collars to reduce crop foraging

Worldwide, crop losses from pests range from 28% to more than 50% of attainable production. This paper discusses the design of elephant collars used to determine if an elephant has entered an exclusion zone. The elephant´s location is determined using GPS. When the elephant enters an exclusion zone a signal is sent to a remote control to indicate the presence of an elephant. In addition, a strobe light and a buzzer on the collar activate to show the presence of an elephant.
