Design of an Arduino Uno-Based Automatic Bird Repellent System for Rice Fields Using Radar Technology

Abstract

Bird pest attacks in rice fields often cause a decline in harvest yields, causing losses for farmers. To overcome this problem, an Arduino Uno-based automatic bird repellent system with radar features that capable of monitoring repelling pests independently. This device integrating two HC-SR04 ultrasonic sensors for distance detection, three servo  motors as mechanical drives, and a buzzer to produce sound effects. All of these  components are controlled by an Arduino Uno microcontroller that processes  sensor data to trigger an instant repellent mechanism when an object is detected.  The implementation results prove that the system is capable of detecting bird  movements in real-time and providing a quick response through a combination of  servo movements and alarm sounds. This innovation offers an effective, efficient,  and economical plant protection solution for farmers.
