Development of Modulated Audible Frequency and Electric Shock Repellent for Rock Dove and Pigeon with Monitoring System

The bird repellent combines sound and shock systems embedded with a simple monitoring system to overview the system's whole activity. The system uses a 4kHz audio frequency proven to be audible to doves and pigeon's hearing. A shock is used and proven tested to induce pain but not lethal to doves and pigeons. This technical research project mainly aims to design circuitry to release electric shock and the modulated audible frequency, develop a program to monitor the birds' occurrence, build the device, and perform a field function test. The system utilizes Raspberry Pi 3 and motion sensors such as ultrasonic and PIR sensors to trigger the whole system and its logging automatically. After a series of tests, the device effectively repels doves and pigeons in the treated area. The T-test value resulted to 10.25, which is greater than t(0.05,19) = 2.093, indicates that the treatment resulted significantly positive after being applied on the test subjects and a Pearson coefficient value of −0.95 demonstrates that the more treatments applied to the infected area, the lesser the population of the birds. Thus, the device can be used in deterring birds not just in urban areas but in farmlands as well.
