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

Advantages
- Real-time occupancy detection: IR sensor modules detect whether each individual parking space is occupied or free.
- Live slot availability shown on an on-site OLED display (current status and free-slot count) plus remote viewing through the integrated mobile app.
- Servo motor–based barrier gate demonstrates automated vehicle entry management.
- LED indicators give at-a-glance visual status of each parking slot — occupied or free.
- Expandable architecture: the design can be extended with more slots and additional parking-management features.
Disadvantages
- Detection accuracy depends on IR sensor positioning and environmental conditions such as ambient light.
- Designed as an academic prototype — a large parking facility would need industrial-grade sensors and additional infrastructure.
- Remote monitoring and mobile-app features depend on network availability.
- Physical parking guidance and vehicle identification are not included unless customised for the deployment.
