How IoT will change smart parking

Smart parking may be a practical IoT application that will dramatically improve everyone’s life.

Imagine, you reach your destination twenty minutes early for a really important meeting. you’ve got a lot of time as long as you’ll find an area to park.

The parking zone for the building is full. You drive around desperately trying to find an area on the road but don’t find one. you are trying the underground parking zone of the building across the road. Driving in, you suddenly need to stop. there’s much traffic before you trying to try to an equivalent thing. You plan to call the meeting to mention you’ll be late and there’s no telephone signal within the underground parking garage.

It takes a half-hour to seek out an area. once you finally reach the office for the meeting, you’re sweating profusely and out of breath. The receptionist tells you that everyone already left. Your meeting was canceled and you’ve got to affect serious losses.

You are not alone. a mean driver within the US wastes $345 per annum, that leads to over $70 billion annually nationwide.

Moreover, 40% of drivers surveyed said that they choose to not visit brick-n-mortar shops thanks to the effort of finding a parking lot.

Recent research is predicting that up to 68% of the people within the world will sleep in major metropolitan cities by 2050. this might have an immediate impact on how car owners park in cities.

How IoT Smart Parking Works

The IoT device sends a periodic update by wireless signal using the MQTT protocol to a cloud server running AWS IoT services. The cloud server assembles data about all parking slots. This shows users via an internet or mobile application the available parking spots to allow them to choose one.

How IoT Sensors Detect Free parking lot

IoT sensors use an ultrasonic wave to detect the space to something. Each sensor is embedded within the parking lot |car parking zone”> parking lot surface and detects the space to the undercarriage of a vehicle if the parking space is occupied.
3 Possible Detection Conditions

  • Space is Occupied: Distance detected to an object by the sensor is within the range of 10 to 50 centimeters (about four to twenty inches).
  • Space is Free: Distance detected to an object by the sensor is quite 50 centimeters (about 20 inches).
  • Space is Dirty: Distance detected to an object by the sensor is a smaller amount than 10 centimeters (about four inches).

If the condition is “dirty” the sensor could also be covered by something or blocked and therefore the device must be checked.

The application runs on AWS IoT and AWS Lambda and shows a driver free spaces in green, occupied spaces in red, and sensor malfunctions as yellow.

IoT Based Smart Parking System Configuration

The amount of parking spaces during a parking zone determines the software and hardware requirements for IoT configuration and system architecture. for giant parking lots, it’s better to use the gateway and therefore the LPWAN protocol for the sensors.

LoRaWAN standard adoption is one among the present IoT trends and therefore the thanks to increasing the operating hours of an autonomous system by reducing power usage. consistent with the specifications of the LoRa Alliance, this reduces the necessity to exchange the batteries. Battery life is extended up to 5 years before needing replacement.

Sensors for IoT Based Smart Parking

Smart parking sensor types include ultrasonic, electromagnetic field detection, and infrared.

Ultrasonic: The accuracy of the sensing is improved by using ultrasound for measurement detection. The disadvantage of this sort of sensor may be a potential blockage by dirt.
Electromagnetic Field Detection: This sensor detects small changes within the magnetic flux when metal things compared to the sensor.
Infrared: this sort of sensor measures changes within the surrounding temperature and detects motion.

Parking 4.0: Future and Opportunities in Smart Cities

Deployment of smart parking systems is predicted to still increase because the technology is extremely useful and makes helpful improvements in lifestyle . the subsequent advanced features are often added to the system to show it into a highly multi-functional management tool.

  • Parking demand management and space optimization
  • Personalized parking guidance
  • Parking reservation systems
  • Dynamic parking prices and policy optimization
  • Detection of parking zones, fees, and overstay violations.


Another innovation uses visual image processing to capture the registration number of a vehicle to acknowledge it with the assistance of Optical Character Recognition technology. Then, it automatically opens the gate to the parking lot |car parking zone”> parking zone and therefore the system guides the driving force to an appropriate parking space. Technologies lying behind this solution are IoT, AI , Machine Learning, Augmented Reality–the same ones that are driving digital transformation for businesses under the “Industry 4.0” term.
