Smart Parking System
An IoT parking solution with per-slot occupancy sensors, live availability, booking and automated barrier control.
Project overview
Ultrasonic or infrared sensors on each parking slot report occupancy to a controller, which publishes state to the cloud. Drivers see live availability in an app, reserve a slot, and the barrier opens automatically on arrival for a valid booking.
The project demonstrates the full IoT stack — sensing, embedded firmware, network transport, cloud persistence and a user application — and the physical model demo is memorable in a review.
Problem statement
Drivers circle car parks looking for a free slot, which wastes fuel and creates congestion at the entrance. Operators have no data on utilisation or peak hours.
Proposed solution
Instrument each slot with a distance sensor, aggregate readings on an ESP32, publish state changes over MQTT to a cloud database, and drive a booking application plus a barrier actuator from that state. Debounce readings so a person walking past does not toggle a slot.
Key features
- Per-slot occupancy sensing with debounced state changes
- MQTT publishing of state transitions only, not continuous polling
- Live availability map in a web and mobile interface
- Advance slot booking with a hold timer
- Automatic barrier control for valid bookings
- Duration-based fee calculation
- Occupancy history and peak-hour analytics
- Offline buffering when the network drops

System architecture
The flow below is what goes into your architecture diagram and the corresponding chapter of the report.
- Sensors measure distance to detect whether a slot is occupied
- Controller debounces readings and publishes only confirmed changes over MQTT
- Broker forwards messages to a cloud subscriber service
- Backend updates slot state, resolves bookings and computes fees
- Client applications subscribe for live availability updates
- Barrier controller receives an open command on verified arrival
Expected output
- Working prototype with a multi-slot model and functioning barrier
- Live availability view updating within seconds of a change
- Booking and billing records
- Occupancy analytics with peak-hour chart

Documentation, review, demo and viva support
Documentation support
Abstract, problem statement, literature survey guidance, system architecture, ER and UML diagrams, module descriptions, test cases and screenshots — prepared in your department format.
Project review support
Delivery is split across your review calendar so review one has a design and plan, review two has working modules, and the final review has the integrated, tested system.
Demo support
A rehearsed demo path, seeded sample data, a reset script, and a recorded walkthrough kept as a backup in case something fails in the review room.
Viva preparation
A written question bank for this domain, a code walkthrough session, and practice at explaining each module in your own words — because the examiner will ask you.
Customisation options
Colleges reject duplicate topics, so most projects are adjusted before we start. These are the usual directions for this one.
- Replace slot sensors with a single overhead camera using number plate recognition
- Add electric vehicle charging bay status
- Add a payment gateway for prepaid bookings
- Add navigation guidance to the assigned slot with LED indicators
