Applications of Technology Assisted Ultrasonic Repellers in Current Era of Indian Agriculture

Agriculture is a mission-critical sector in India, employing nearly half of the country's workforce and contributing significantly to the economy. Many researchers are contributing to it by researching in various areas like monitoring crop health, monitoring applications with the help of IoT and computer vision, predicting diseases, automated pest control, yield enhancement, smart irrigation, precision agriculture etc. Although ultrasonic repellers are electronic devices that emit high-frequency sound waves intended to repel pests such as rodents, insects, and birds; these devices are also marketed as a safe and humane alternative to traditional pest control methods, which often involve the use of harmful chemicals and physical traps. In this work, we present the pros and cons of ultrasonic repellers in the agriculture sector in India and across the globe. We present various ways for repelling animals from crop damage and provide a discussion as to why ultrasonic repellers are a way into the future for pest control. They are safe, clean, optimized and provide a plethora of managing utility to the agriculturist without harming the animals and minimizing the involvement of manual human labor and thereby reducing human-animal conflict in the process. We discuss whether it is practical for Indian farmers to opt for ultrasonic repeller instruments for smart agriculture or not. In the end, we present the challenges and future work for the area followed by the conclusion of this work.
