Abstract:
Agricultural Crop Damage Due To Herbivorous Animal Intrusion Causes Annual Losses Exceeding USD 2.5 Billion In India Alone. This Paper Presents An IoT-based Smart Herbivore Detection And Deterrence System That Autonomously Monitors An Agricultural Field Boundary Using A Passive Infrared (PIR) Motion Sensor, Activates An Acoustic Buzzer Deterrent With An Irregular Non-repetitive Alarm Pattern, Drives An L298N Motor Module To Animate A Physical Scare Mechanism, Captures Evidence Images Using An OV7670 CMOS Camera, And Persists All Event Records To A Micro SD Card — All On An Arduino Uno (ATmega328P) Microcontroller Platform. Laboratory Validation Across 300 Trials Confirmed An Overall PIR Detection Rate Of 91.2%, Deterrence Response Latency Under 80 Ms, And SD Card Logging Reliability Of 99.8% Over 8-hour Endurance Tests. The System Is Deployable From A USB Power Bank With A Total Bill Of Materials Cost Under INR 1,800.
