IoT Smart Parking System with Live Slot Tracking and Mobile App

Traditional parking systems often require drivers to manually search for available parking spaces, causing unnecessary waiting time, fuel consumption, and congestion inside parking areas.
This project demonstrates an automated parking assistance system that uses IoT-enabled sensors to monitor parking slot availability and provide real-time information to users through a display and mobile interface.

1. IR sensors installed at each parking slot continuously detect whether a vehicle is present.
2. The ESP32 microcontroller collects sensor readings from all parking spaces.
3. The controller processes the occupancy information and determines available and occupied slots.
4. Slot status is displayed locally using an OLED display.
5. The IoT communication system transfers parking information to the mobile application (implementation dependent).
6. When entry access is required, the servo motor operates the barrier gate mechanism.
7. Users can check available slots and receive parking status updates through the connected interface.

Real-Time Parking Slot Detection — IR sensor modules detect whether individual parking spaces are occupied or available.
Live Slot Availability Display — OLED display shows current parking status and available slot count.
Mobile Application Integration — Provides a mobile interface for viewing parking slot availability remotely.
Automated Entry Barrier Control — Servo motor-based barrier gate demonstrates automated vehicle entry management.
Slot Booking Indication — Displays selected or reserved slot status through the connected system.
IoT-Based Monitoring — Enables connected monitoring of parking data through embedded hardware.
LED Parking Status Indicators — LEDs provide visual indication of occupied and free parking spaces.
Expandable Parking Management Design — System architecture can be extended for additional slots and features.

Prerequisites:
• Basic understanding of electronics and embedded systems.
• Knowledge of ESP32 programming concepts.
• Familiarity with IoT communication concepts.
• Basic understanding of mobile application usage.
• Power supply availability for prototype operation.

Limitations:

1. Prototype accuracy depends on IR sensor positioning and environmental conditions.
2. The system is designed as an academic prototype and may require industrial-grade sensors for large parking facilities.
3. Mobile application and cloud connectivity features depend on the selected implementation.
4. Physical parking guidance and vehicle identification are not included unless customised.
5. Network availability may affect remote monitoring features.
6. Large-scale deployment requires additional hardware and infrastructure planning.
