This document presents a border alert system for fishermen using Received Signal Strength Indicator (RSSI) technology. The system uses a PIC microcontroller connected to an RSSI module, GPS, and LCD display. When a fishing boat reaches the border area, the system will alert the fishermen. It continuously monitors the boat's location provided by the GPS and compares it to the defined border area. If the boat crosses into the border area, an alert is sent to both the fishermen and border security. The system aims to safely guide fishermen and prevent them from unintentionally crossing borders. It provides real-time location tracking and reporting to help reduce human losses. The proposed system is easier to operate, more flexible,
