This document describes a smart farmland system that uses Raspberry Pi to detect animal intrusions and prevent crop damage. The system utilizes RFID tags injected into animals, along with an RFID reader and GSM modem. When an animal enters the farmland, the RFID reader detects its tag and sends an SMS alert to farmers and forest officers. It then uses noise from a speaker and smoke from a fog machine to irritate and repel the animal back to the forest without harming it. The system aims to provide an effective solution to the widespread problem of animals damaging crops in a more humane way compared to traditional electric fencing.
