Farmers lose a lot of money when wild animals damage their crops. Old-fashioned ways of protecting things, like manual guarding, are hard work and don't work. This project shows how to use an IoT system to protect crops automatically. It uses an ESP8266 microcontroller with an ultrasonic sensor to detect intrusions, a DHT11 sensor to monitor the environment, a rain sensor to detect weather, a servo motor to physically deter intruders, and a buzzer to make noise. All of these parts are housed in a weatherproof acrylic box. The system turns on the servo motor and buzzer to scare the animal away when the ultrasonic sensor sees it within the set range. The Blynk IoT platform sends real-time alerts with sensor data to the farmer's smartphone. This lets them monitor and control things from afar. It also keeps an eye on rainfall, temperature, and humidity, giving you a complete picture of your farm. The system is cheap, uses little energy, and protects you automatically 24 hours a day, seven days a week. Field tests show that the system can reliably detect intrusions, respond quickly, and greatly reduce damage to crops. This solution gives farmers a cheap and useful way to protect their crops and keep people and animals from fighting.
