Ultrasonic Sound Emission System for Protecting Crops and Enhancing Productivity by Deterring Monkeys.

Abstract

This project presents the development of a wireless sensor system th at utilizes ultrasonic sound to deter monkeys from invading agricultural fields and damaging crops. Monkeys pose a significant threat to farmers, leading to substantial crop losses. The proposed system employs a series of buzzers to emit ultrasonic frequencies that irritate monkeys, thereby preventing them from approaching crops. Sensor Calibration: • Proper calibration of the PIR sensors is essential to ensure accurate detection of monkey movements. There is a risk of false positives triggered by other animals, environmental factors, or moving objects, which could lead to unnecessary sound emissions. Achieving the right balance in sensitivity and detection range is critical for the system's reliability and overall effectiveness. Habitat Impact: • Introducing ultrasonic sound as a deterrent can potentially disrupt the local ecosystem. Other species, especially those with sensitive hearing, may be adversely affected by the sound waves emitted by the system. This raises ethical concerns regarding the unintended consequences of deploying such technology in wildlife management. Weather Conditions: • The performance of the ultrasonic sound system can be influenced by varying weather conditions. Rain, humidity, and extreme temperatures may affect the functionality of electronic components and the propagation of sound waves. These environmental factors can compromise the system's reliability and effectiveness in deterring monkeys.

Specification

Description:This project presents the development of a wireless sensor system th at utilizes ultrasonic sound to deter monkeys from invading agricultural fields and damaging crops. Monkeys pose a significant threat to farmers, leading to substantial crop losses. The proposed system employs a series of buzzers to emit ultrasonic frequencies that irritate monkeys, thereby preventing them from approaching crops. , Claims:Claim 1: A solar-powered ultrasonic deterrence system for crop protection, comprising motion sensors, ultrasonic buzzers, an LDR sensor, a charge controller, a rechargeable battery, and a central control unit, wherein the system detects motion and activates ultrasonic sound emissions that are unpleasant to monkeys, thereby deterring them from entering the protected area.
Claim 2: The system of Claim 1, wherein motion detection is achieved through Passive Infrared (PIR) sensors, strategically placed around the field to provide comprehensive coverage.
Claim 3: The system of Claim 1, wherein the ultrasonic buzzers emit sound at a frequency intolerable to monkeys, encouraging them to leave without causing harm to humans or other animals.
Claim 4: The system of Claim 1, wherein the solar panel is connected to a charge controller that regulates power flow to a rechargeable battery, ensuring continuous and self-sustaining power supply, making the system suitable for remote agricultural locations.
Claim 5: The system of Claim 1, wherein the LDR (Light Dependent Resistor) sensor detects low-light conditions and automatically activates LEDs at night, providing an additional visual deterrent to discourage wildlife intrusions.
