India is an Agriculture-dominated country. Also the population of India is second largest in this whole world. In this situation crop protection is as important as crop production. We have designed a device that can improve crop protection from wild life attacks. A proposed device designed to protect crops not only from birds, but also from wild animals. It is also intended to detect any type of fire in the vicinity of the cropland. It can also detect soil moisture levels and alert farmers if they become too low or too high. We conducted an experiment in this research study to investigate the impact of various chemical repellent along with repeller sounds on Animals. To reduce crop destruction, we are using ultrasonic frequency generator in our model that will act as a repeller. But after a certain period of time, they become habituated of it. So, we have conducted an experiment to check the pattern of their behavior against this frequency and also we have experimented with various types of sound to repel the wild animals from crop-field. Based on this pattern we can improve the repeller system
