Automatic Unauthorized Parking Detector With SMS Notification To Owner
A system that detects vehicles parked in no-parking zones and alerts the owner by SMS. Each vehicle carries an RFID tag; a reader in the no-parking area identifies it, and if it stays beyond a set time a GSM module sends a warning and fine notice.

How the Automatic Unauthorized Parking Detector With SMS Notification To Owner works
- 12 V power adapter / step-down transformer supplies the circuit; a regulator gives the controller and sensors a steady 5 V.
- The Push buttons and switches provide manual inputs and the power switch.
- The ATmega328P microcontroller with base board is the brain of the circuit: it samples the sensors, compares readings with set limits and switches the outputs.
- The RFID reader with tags reads the unique ID of an RFID card or tag held near it so the system can identify the user or item.
- The GSM module sends SMS alerts or makes calls to the registered phone number using a normal SIM card.
- The LEDs indicate status.

E&TC / ECE viva questions on this project
What is the aim of the Automatic Unauthorized Parking Detector With SMS Notification To Owner project?
A system that detects vehicles parked in no-parking zones and alerts the owner by SMS. Each vehicle carries an RFID tag; a reader in the no-parking area identifies it, and if it stays beyond a set time a GSM module sends a warning and fine notice.
Explain the working of your project in short.
12 V power adapter / step-down transformer supplies the circuit; a regulator gives the controller and sensors a steady 5 V. The Push buttons and switches provide manual inputs and the power switch. The ATmega328P microcontroller with base board is the brain of the circuit: it samples the sensors, compares readings with set limits and switches the outputs. The RFID reader with tags reads the unique ID of an RFID card or tag held near it so the system can identify the user or item.
Why is a microcontroller used in this project?
A microcontroller combines a CPU, memory and I/O pins on one chip, so a single low-cost IC can read sensors, make decisions in code and control loads without a computer.
Why is a pull-up resistor needed with a push button?
Without it the input pin floats and reads random values. The pull-up keeps it HIGH until the button connects it to ground.
How does RFID work?
The reader produces a 13.56 MHz (or 125 kHz) field that powers the passive tag through induction. The tag replies with its stored unique ID, which the controller compares with its list of authorised IDs.
How does the GSM module send an SMS?
The microcontroller sends AT commands over serial, for example AT+CMGF=1 to select text mode and AT+CMGS with the phone number followed by the message. The module transmits it over the mobile network.
Why is a resistor connected in series with an LED?
It limits the current to a safe value (about 10–20 mA). Without it, the LED would draw too much current and burn out. R = (supply voltage − LED voltage) ÷ current.
Explain the block diagram of your project.
The input section senses the real-world quantity, the ATmega328P microcontroller with base board processes it according to the program, and the output section acts locally and sends the data or alert wirelessly. The power supply section feeds every block.
Which communication protocols are used between the modules?
UART (serial) for the GSM, GPS, Bluetooth or fingerprint modules and SPI for the RFID reader or radio module. Each protocol was chosen because the module supports it and it uses the fewest pins.
What is the operating voltage of the circuit?
The controller and most sensors work at 5 V (ESP boards and some modules at 3.3 V). A 12 V adapter powers the board, and a regulator steps it down. Motors and relays get their own supply line so they do not reset the controller.
