Today the microprocessor and microcontroller play a vital role in automation of almost all systems. This paper reports the safeguard of farmland from wild animals. The proposed system uses Raspberry Pi controller to identify the animals by producing high frequency pulses. This is possible by producing ultrasonic sound in the frequency that irritates the animals. The experimentation is developed with Passive Infra-Red (PIR) sensor, camera, Raspberry Pi, power amplifier and high frequency ultrasonic speaker. The camera is triggered to take a picture of the animal when the PIR sensor detects the presence of an animal and the animal is identified. The Raspberry Pi is used to produce high frequency pulse related to the identified animal. The pulse produced is not enough to drive the high frequency ultrasonic speaker; as a result the pulses are amplified by power amplifier and fed to the speaker. The proposed system keeps the beasts away from the crops without hurting them and the danger of getting electrocuted can be prevented. The ultrasonic noise is indistinct to individuals and has no impact on humans.
