This project work presents the study and design of PLC based Multilevel Automatic car parking system. Car parking is a major problem in urban areas in both developed and developing countries. Due to increase number of cars on roads there is a problem car parking. Multilevel Car parking is the most efficient way of parking as by using this arrangement we can park more number of vehicles in least possible area. This system also gives the number of cars parking in parking slot and also gives parking slot is full or empty. In this project basically, we have made 2 floors and 6 parking slots and every parking slot consist of individual sensors and entry and exit gate also consist sensor .When the car is coming at entry gate the main gate is not open if all the parking slots is full, if there is a parking slot free, the main gate is open and this opening and closing of gate is controlled by using PLC and no require of manual labours. If the car is parking in that place the sensors give signal to the PLC. If there is a vehicle in the entry gate the space is available in second floor, the person will not have to search the parking in individual floors. The system will indicate number of free slots in every floor then he can directly go to the floor where the space is available and park the vehicle. This system automates the entire process of parking which reduces human error and make best use of the available space, which in turn results in highest security. Due to these advantages, this system can be used in societies, airports, railway stations or any other place where crowding of vehicles is observed.
