Solar based Smart Cropping Defence System using IoT based on Birds and Animals

Preserving their harvest from wild animals and unauthorized intrusions is a significant difficulty for farmers. The Farm Guardian, a solar-powered, IoT-enabled automated crop protection system, helps solve this. This technology uses an ESP8266 NODEMCU microprocessor alongside touch sensors and ultrasonic sensors to detect movement and touch. Should dangers be discovered, the HCSR04 ultrasonic sensor's continuous object distance monitoring sets off a buzzer and warning system. A solar-powered electric fence keeps animals or trespassers off the perimeter, hence enhancing security by means of a slight deterrent shock. Using the Blynk app, the system sends alerts and actual data to an Android phone belonging to a farmer, therefore enabling remote monitoring effective operation with a 12V solar photovoltaic power source changed to 5V DC for the control unit and sensors. Output modules for buzzers, LED indicators, a servo motor, and a user interface LCD screen constitute the system. Automated, affordable, environmentally friendly means of crop protection using renewable energy is provided by Farm Guardian. The suggested strategy maintains ecologically sustainable farming methods, secures the farm efficiently, decreases dependence on traditional fences, and lowers human interference.
