Introduction to Smart IoT Parking System

The rapid increase in vehicles has created serious parking challenges, particularly in urban areas. However, parking spaces and road infrastructure have not expanded at the same rate. To address this issue, the Smart IoT Parking System using RFID and an Android application provides an automated parking solution. The system combines RFID-based access control, real-time slot monitoring, and mobile connectivity. As a result, it reduces manual effort, saves time, and makes parking more convenient.

Key Features

The Smart IoT Parking System includes several features that improve parking efficiency. First, it provides automatic access with minimal human involvement. An RFID scanner verifies the user’s identity and account balance before allowing entry. In addition, automatic gate barriers manage vehicle entry and exit smoothly.Meanwhile, IR sensors monitor individual parking slots and detect whether they are occupied or available. The Android application also allows users to check parking availability in real time. Furthermore, the system improves security by allowing access only to valid RFID cards with sufficient balance.

Specifications of Smart IoT Parking System

A microcontroller acts as the main processing unit of the system. It receives signals from the RFID scanner and IR sensors to verify users and monitor parking slots. Meanwhile, the ESP8266 Wi-Fi module connects the system to the IoT platform and enables real-time data communication.The IoT Gecko server processes the collected information and displays parking data through the Android application. In addition, DC motors operate the entry and exit barriers. Each parking space contains an IR sensor, which helps provide accurate information about available and occupied slots.

Significance

The Smart IoT Parking System can improve parking management in busy urban areas. By combining RFID access control with IoT-based slot monitoring, it helps drivers find available spaces more efficiently. Moreover, automated monitoring reduces the need for continuous staff supervision and supports better use of parking capacity.At the same time, RFID authentication strengthens parking security by restricting access to authorized users. The Android application provides instant parking information, allowing users to check availability before reaching the parking area. Therefore, the system can reduce unnecessary searching, improve convenience, and support more efficient parking management.

Conclusion of Smart IoT Parking System

In conclusion, the Smart IoT Parking System using RFID and an Android application provides a secure and efficient approach to modern parking management. It automates access control, monitors parking slots, and delivers real-time information through mobile connectivity. Furthermore, the system reduces manual work while improving user convenience and security. Overall, this IoT-based solution demonstrates how connected technologies can address everyday parking challenges and support smarter urban infrastructure.

Function: Four IR sensors monitor the parking slots. The LCD displays the number of free spaces. An SG90 servo represents the barrier gate and a buzzer indicates a full parking area.

Connections

IR sensor VCC → 5V and GND → GND. SG90: red → 5V, brown/black → GND, orange/yellow → D6. A dedicated entry IR sensor is recommended for a truly automatic barrier; the listed kit does not include one.
