The automatic multistory car parking system aids in the reduction of parking space. In today’s world, when parking has become a major issue, it is critical to prevent wasting space in modern large corporations, residences, and other buildings. This approach is beneficial in areas where more than 100 cars must be parked since it reduces space waste. This automatic automobile parking system allows vehicles to be parked floor by floor, minimising the amount of space required. Depending on the need, any number of cars can be parked here. As a result, the system is modernised and, as a result, space-saving. The 8051 microcontroller was used to build this concept.


On the ground floor, there is a display that is essentially a counter that will tally the number of automobiles on each floor and display a message based on that information. On the ground floor, there is also a gate that is operated by a stepper motor. An IR pair is installed in front of the gate to detect when the car has approached the gate. If a car passes between the two IR pairs, for example, the LCD will display the specific floor on which the automobile can be parked. The gate will automatically open as soon as the car passes through the second IR pair. On each floor, a green and red led indicator is retained to show whether the car can be parked on that floor or not. If the green led on any given floor glows, it means that floor is empty and you can park your car there. However, if the red led on that floor glows, it means there is no vacancy on that floor; in that case, you can park your automobile on the next floor, as indicated by the signal.

If no parking space is available, all red floor indicators will illuminate, the LCD will read “NO SPACE FOR PARKING,” and the gate will remain closed.

The 8051 microcontroller is used to write the programme. It connects all of the circuits together.


London, like New York and Delhi, has more than five million automobiles and two-wheelers on its roadways, but there aren’t enough parking spots. In the main markets of Delhi, demand for parking space has outstripped supply by 43% on average. It is not simply a problem in Delhi or Mumbai; all of India’s major cities are experiencing space constraints. In other cities such as Kolkata, Bangalore, Hyderabad, Ahmedabad, Chandigarh, Pune, and other metropolitan and semi-urban areas, parking is quickly becoming a big issue.Because they often require less building volume and ground area than a conventional facility with the same capacity, multi-story car parks have cheaper construction costs per parking space.

Multi-story parking garages provide the most options for achieving the best parking solution. Vertical and horizontal movements take occur at the same time, reducing time and assuring quick parking and retrieval.


Drivers who use multi-story parking facilities, sometimes known as parking garages, typically benefit from a variety of amenities. Despite its ability to accommodate a huge number of vehicles, multi-story parking garages have a number of drawbacks that stem from their towering, confined, and typically darkly illuminated character.

1.Deterioration and Maintenance

Hundreds of thousands of pounds of vehicles, people, and equipment are supported by multi-story parking structures every day. Because the garages carry a lot of weight and loads that change all the time, they deteriorate quickly if maintenance isn’t done on a regular basis. Changing weather and climatic conditions can also damage a garage’s steel support structure, providing an unhealthy environment for garage users, according to Canada’s National Resource Council. According to the National Resource Council, a variety of corrosion inhibitors can assist delay processes that eat away at the structure’s integrity, but anti-corrosion methods must be included in routine maintenance and upkeep to keep multi-story parking facilities structurally sound.

2.Parking Angle Considerations

Because many different types of vehicles drive in, around, and out of parking garages on a daily basis, planners must pay careful attention to how parking spots are configured within the structures. Two-way traffic flow in a multi-story garage provides a number of parking issues for drivers and designers, according to architects Sakri and Khairuddin in a municipal parking garage presentation. Parallel parking, for example, wastes valuable space, yet straight parking places are difficult for some drivers to navigate. Other methods, such as angled parking, are ineffective in two-way traffic and can only be used in garages with separate entrance and exit holes.


While most parking lots, multi-story or not, require some type of lighting when they are open at night, the multi-story nature of parking garages necessitates several lights throughout the building. Furthermore, because the inside of the structure may be gloomy even during the day, many of these lights must be turned on all of the time. Garage owners may face expensive energy expenses as a result of this arrangement, which may necessitate frequent lighting maintenance to replace faulty or burned-out bulbs.


Some security professionals are concerned about the safety of multi-story parking garages because they allow limited natural light inside. Architects Sakri and Khairuddin advocate security systems that are directly connected to local police or public safety stations in their municipal presentation. Furthermore, the architects express a desire to decrease gloomy areas where criminals might hide. Even with security systems in place, criminals appear to thrive in multi-story parking structures; one parking garage user voiced irritation in a 2009 article in the Chicago Sun-Times after having three burglaries in two years.Sai Krishna filed this project report.

In today’s packed cities, car parking is a huge concern. There are simply too many cars on the road and insufficient parking spaces. As a result, effective parking management systems are required. As a result, we demonstrate the usage of an IOT-based parking management system that allows for efficient parking spot utilisation. We use IR sensors to detect parking space occupancy and dc motors to replicate gate opener motors to show the concept. For internet connectivity, we now use a wifi modem, and the system is controlled by an AVR microcontroller. For internet connectivity and IoT administration GUI design, we use IOTGecko. Using infrared sensors, the system identifies whether parking spaces are occupied.

It also uses infrared technology to detect when a vehicle approaches the gate for automated gate opening. The system reads the number of available parking slots and updates data with the cloud server so that parking slot availability may be checked online. Users can check for available parking spaces online from any location and park without fuss. As a result, the technology tackles the parking problem for cities while also providing users with an effective IOT-based parking management system.

The smart car parking system operates on the simple idea of detecting an obstruction and providing visual feedback. The proximity sensor, which consists of an Infrared emitter and a receiver, is positioned on the parking lot’s ceiling. Infrared rays are emitted by the IR emitter, and these rays generally bounce off objects. The IR receiver picks up these rays and converts them to an electrical signal, which causes a potential difference. The ensuing potential difference aids in the circuit’s completion. The LEDs are set along the driveway and turn on when the sensor detects motion. The potentiometer is used to calibrate a threshold distance depending on the average height of vehicles for sending and receiving radiations. To provide resistance, resistors are used.

Automation is a positive step toward a prosperous future in the transportation industry. This design provides a practical solution to the situation at hand. When the threshold distance was calibrated and the barrier was recognised, the smart automobile parking system was created, built, and tested to provide accurate results. The switching of LEDs based on the presence of a car in the parking area was instantaneous in both the absence of a vehicle and the detection of a vehicle.

The design is adaptable and may be changed to fit the space available, and it can even be fitted in a small, cramped space. A common information board is presented based on the amount of Yellow LEDs detected, indicating the number of parking places available.

In an IR system, an infrared receiver sends signals to control and operate equipment. A photodiode is the most important part of the IR receiver. A semiconductor that turns light into electrical energy is known as a photodiode. When photons are absorbed in the photo diode, current is created.

These gadgets, like a television or a cable box, pick up infrared signals from your remote control. The signals are amplified and encoded for transmission after receiving the infrared rays. Because line-of-sight transmission is required, receivers must be situated in the area you plan to use.

It is feasible to combine an IR transmitter and receiver with another component to extend the range of an infrared remote control. An extension that is hardwired
