An impression of the finished product
(AI generated)


To start of our idea we had to think about the basic functionalities like:

  • How is a car being detected?
  • Which sensors are needed?
  • Which parking spots are we supporting?
  • How is our product being charged?
  • How is it the data received?
  • How can we accomplish the connections and ensure redundancy?
  • Which database is being used?
  • How do we use/safe data?
  • How should the application look like?

The project should include the following features:

  • An application which displays free parking spaces
  • GPS records of every LotSpot placed
  • Infrared proximity sensor which detects a free and occupied parking lot
  • A Wifi-module which transmits the data to a gateway (in our case a Hotspot)
  • A battery pack which insures redundancy in case of a power failure
  • Direct connection to the power grid


We needed these resources to implement the functionality. For copyright reasons we do not want to share our complete design


We displayed some parts we used to implement our project.







  • Google Firebase
