Landmines, while effective in securing territories during warfare, pose a significant threat to military personnel even after deployment, often resulting in accidental injuries or fatalities among friendly forces. This research presents the design and implementation of an intelligent [1] RF-based landmine deactivation system aimed at preventing unintended detonations for friendly soldiers while maintaining full functionality against enemy intrusions. The system is divided into two units: a transmitter embedded in the soldier's footwear and a receiver integrated within the landmine. When a friendly soldier, equipped with the RF transmitter, enters the proximity of the landmine, the receiver detects the signal and activates a relay to disconnect the detonation mechanism. In contrast, if an enemy without a valid transmitter approaches and steps on the landmine, the system remains armed and triggers upon pressure activation. The RF communication is facilitated using 434 MHz modules along with HT12E and HT12D encoder-decoder pairs for signal transmission and reception. This low-cost, efficient system demonstrates a selective activation mechanism that significantly enhances battlefield safety for [2] friendly troops. The project lays the groundwork for future integration of encrypted communication, [3] GPS tracking, and centralized control, contributing toward the development of smarter, more humane defense technologies.
