Project Name : A Modified Radio Collar with Enhanced Functions.
Theme Name : Environmental Issue and Concerns
There are two different types of collars which can be tied around the neck or any other part of an animal. It works on the principle of contraction and relaxation in an animal‟s tissue region of the throat brought about by the process of breathing.
Another collar is based on the principle of expansion in animal‟s tissues when it confronts a threat.
The names given to the two collars are „The Orb‟ and the „The Sentinel‟.
The best part of these two collars (in the form of working models) is that they are made from waste materials costing just around `100/-.
