Summary of the Project: Location-Based Smart Door Lock System

Project Overview

• Title: Location-Based Smart Door Lock System
• Objective: Prevent unauthorized access by detecting abnormal door lock activations and notifying the user based on location data.
• Submission Date: June 8, 2023
• Course: IoT Solutions (Inha Technical College, Computer Information Engineering)
• Project Leader: 김대현 (Computer Information Engineering, ID: 202347020)

Key Features

1. Door Lock Monitoring:
   • Detects door lock states (inactive, active, abnormal) by analyzing current flow:
     • Inactive: 0 mA
     • Standby: ≤ 20 mA
     • Active: 100 mA
     • Overvoltage: 400–500 mA
   • Transmits current data every second to ThingSpeak via API.
2. Location-Based Alerts:
   • Checks the user's registered smartphone location using GPS coordinates.
   • Notifies the user if the lock is activated while their phone is outside the home radius.
   • Provides options for forced lock or emergency notifications to authorities.
3. Real-Time Communication:
   • Utilizes IoT platforms (ThingSpeak, IFTTT, AWS) for communication between the lock and the main server.

Development Environment

1. Hardware:
   • Raspberry Pi 3B+
   • Microsoft Surface Book 3
