Abstract

Many people have problems with pest rodents. Rats eat our crop, contaminate our stored food, damage our buildings and spread dangerous diseases to people and livestock. In this project, the ultrasonic repelling device has been developed to solve the problem in controlling the population of rats and scared them away from entering paddy field. This project uses Passive Infrared Sensor (PIR) to detect the motion of rat up to 20 feet away by using a Fresnel lens and infrared sensitive element to detect changing patterns of passive infrared emitted by objects in its vicinity. The detection of the ultrasonic repelling device is controlled by PIC16F876A microcontroller. The microcontroller gets its input from detector circuit and the output emits high frequency ultrasonic wave to expel intruding rats away. Therefore, the main focus is to study the detection mechanism of motion to PIR and program the PIC microcontroller to produce the ultrasonic wave.
