Songram-M071 is a prototype Smart Area Denial System designed to modernize tactical defense operations. Unlike traditional static countermeasures, Songram-M071 utilizes a Master-Slave architecture (ESP32 + Arduino) to provide remote arming/disarming, real-time GPS tracking, and "Friend-or-Foe" (IFF) identification via a centralized Command & Control (C2) dashboard.

Traditional landmines are hazardous static assets that pose long-term risks to friendly forces and civilians. Songram-M071 mitigates these risks through active state management.
| Traditional Landmine Issues | Songram-M071 Engineering Solutions |
|---|---|
| ❌ Friendly Fire Risk | ✅ NFC/RFID Identification: The system detects "Friendly" ID tags and automatically suppresses the trigger mechanism, logging the event as "Safe Passage" instead of detonation. |
| ❌ Irreversible Activation | ✅ Remote State Management: Can be remotely toggled between Active (Armed) and Inactive (Safe) modes via the Dashboard using low-latency MQTT packets. |
| ❌ Zero Visibility | ✅ Live Telemetry: Streams real-time GPS location, battery voltage, and operational status to the Command Center to prevent lost ordinance. |
| ❌ "Dumb" Hardware | ✅ Environmental Sensing: Onboard sensors relay local weather data (Wind Speed/Temp) to HQ to aid in broader tactical planning. |
This project demonstrates a high-reliability "Edge-to-Cloud" implementation optimized for sub-50ms latency:
- The "Sentry" (ESP32): Handles Wi-Fi/GSM connection, parses MQTT payloads, and reports battery voltage/status. It acts as the primary gateway.
- The "Trigger" (Arduino): Dedicated to handling sensor interrupts (pressure/vibration) with microsecond precision, ensuring no trigger event is missed.
- The "HQ" (React Dashboard): A secure admin panel for monitoring the fleet, featuring OpenStreetMap integration for geospatial visualization.
- Hardware:
- ESP32: MQTT Client & Wi-Fi Gateway.
- Arduino: L298N Motor Driver Interface & Sensor Logic.
- Sensors: GPS Module, Environmental Sensors, NFC Reader.
- Communication Protocol: MQTT (Message Queuing Telemetry Transport) for secure, low-bandwidth communication in unstable network environments.
- Frontend Interface: React.js, Leaflet Maps API, CSS Modules (High-Contrast Tactical UI).
- Backend: Node.js (MQTT Broker management).
- 📍 Geospatial Intelligence: Visualizes the exact deployment location of every unit on a satellite map.
- ⚔️ Remote Activation (Arming): Features a "Landmine Activation" toggle that physically arms/disarms the unit remotely.
- 🆔 IFF Logic (Identification Friend or Foe): As seen in the console logs, the system distinguishes between "Soldier" (Friendly) and "Enemy" triggers based on RFID signatures.
- 🔋 Power Efficiency: Implements deep-sleep cycles on the ESP32 to extend field operational time.
- ESP32 ↔ Arduino: UART Serial Communication (RX/TX).
- Motor/Trigger Mechanism: Connected to Arduino Digital Pins (PWM).
- Power Distribution: Shared Ground (GND) is critical between the logic layer (ESP32) and the mechanical layer (Arduino/Drivers).
