Description
The Smart Parking Lot project automates parking spot allocation using sensors and tracks the time a car is parked for billing. The system provides real-time parking availability and uses a web interface for monitoring.
Motivation
I chose this project to address the need for efficient parking management in crowded urban environments. The goal is to optimize parking space usage and provide real-time data to drivers.
Architecture
Schematic Diagram
The architecture of the Smart Parking Lot system includes the following main components:
- Parking Sensors: Detect free parking spaces.
- Microcontroller (Raspberry Pi Pico W): Collects data from sensors and processes the information.
- Web Interface: Displays real-time parking availability and billing info.
- Database: Stores parking data such as time parked and billing information.
How they connect:
- The Raspberry Pi Pico W communicates with the parking sensors to detect free or occupied spots.
- The microcontroller sends the data to the web interface, allowing users to view available spots.
- The system tracks parking time and calculates the bill based on the time spent.
