Abstract: All around India, the birds are a major threat in the area of college causing damage to buildings and college area, also make dirty human living areas. But now a day with the change of Technology. We would like to propose the model and prototype of the digital bird repeller system using IoT devices. This model is consists of the main functionality, a PIR sensor that will detect the bird and generate the sound using megaphones which will drive the bird away from the college area. This model aims to maximize the yield output & shows how IoT devices can help achieve this.

Keywords: Internet of things (IoT), PIR sensor, Arduino Megaphones, Battery, Amplifier.
