This project proposes a parking system to solve the problem of inessential time consumption in finding parking space in college campus car park areas. The proper operation of these systems depends on their ability to detect the presence of vehicles in the parking spaces. A parking reservation system is established in such a way that users book their parking slot through short message services (SMS). A communication device called GSM used to send a SMS to the user. Once the sensor range is below some fixed range, so the RFID tag stops transmitting the data, and the system recognizes the slot as booked. The micro controller will send the information of booking slot details. An Android based application is used to commanded the entering to or leaving from the parking slot.
