This document describes an IoT-based smart parking system that uses sensors to detect empty parking spots and a mobile app to help drivers find available spots more easily. The system includes IR transmitters and receivers attached to each parking spot to detect when a spot is empty. WiFi modules gather this data and send it to a central gateway, which stores the information in the cloud. The mobile app allows users to view available spots near their destination, reserve a spot, and pay for parking digitally. The system aims to reduce traffic and make parking more convenient, contributing to the development of smarter cities.
