Design and Implementation of a Solar-Powered IoT Platform for Intelligent Crop Pest Control

The High-tech Scarecrow is an intelligent, solar-powered device developed to safeguard farms from birds and animals. Unlike traditional scarecrows, which are passive and often fail to prevent crop damage, this advanced system employs an ESP32 microcontroller along with ultrasonic and PIR sensors to detect motion around the field. When movement is sensed, it triggers an APR9600 voice module to emit pre-recorded warning sounds and operates a moving scare mechanism to deter intruders. It runs on solar energy supported by a rechargeable battery, ensuring uninterrupted, eco-friendly performance. Built-in LCDs provide operational status, enhancing ease of use. This smart, low-cost solution integrates IoT and renewable energy, offering a reliable and expandable approach for today’s farmers, with future possibilities like AI-based detection and remote monitoring via the internet of things.
