# Smart Parking System

The **Smart Parking System** is an IoT-based solution designed to help drivers quickly locate vacant parking spaces. It automates entry/exit gates, tracks occupancy in real-time, and displays availability on an LCD screen and a mobile app. This system reduces parking time, minimizes congestion, and enhances user convenience through IoT automation.

## Key Features

- **Automated Gate Control**: IR sensor triggers servo motor to open/close the gate.  

- **Real-Time Occupancy Tracking**: Counter increments/decrements as vehicles enter/exit.  

- **Dynamic Display**: LCD screen shows available slots at the entrance.  

- **Mobile App Integration**: MQTT protocol updates parking status on a smartphone app.  

- **Capacity Management**: Blocks entry when parking is full.  

## Hardware Components

- **Raspberry Pi 3b+**: Central processing unit.  

- **IR Sensors**: Detect vehicle presence at gates and parking slots.  

- **Servo Motor**: Controls gate barrier (90° rotation).  

- **LCD Display**: Shows live parking availability.  

## Software & Technologies

- **Raspbian OS**: Operating system for Raspberry Pi.  

- **MQTT Protocol**: Enables app communication (publish-subscribe model).  

- **Custom Mobile App**: Built to display parking status remotely.

## How It Works

1. **Entry**:  

   - IR sensor detects a vehicle → Servo motor opens the gate.  

   - Counter increments; LCD and app update available slots.  

2. **Exit**:  

   - IR sensor triggers gate opening → Counter decrements.  

3. **Full Capacity**:  

   - System denies entry if slots are occupied.  

## Future Scope

- Integrate payment systems for reserved parking.  

- Add solar panels for energy-efficient operation.  

- Implement license plate recognition for security.
