Parking guidance system recommendation

[wolfrose]

Hi,

My work asked me to search for a commercial or diy project for parking guidance system.

They aren't interested in putting a sensor at each parking spot.

So I suggested of just implanting a counter at the enter/exit gate and put a big display, and then put secondary counters at the right/left sides of the parking area with their displays.

Here's my plan for the implementation plan:

This is my quick illustration for system parts:

The problem now is how to find the proper displays that of course in big size ? I've working with P1 displays before but the the system was pre-programmed and linked with a special software to upload the messages you want to display.

But here I need to get information from counters and send the counting information to the displays.

Or instead, just one counter at the main gate and put the sign at the top which is enough to display how many available parking slots for the right and left side:

And cancel part 2 & 3.

But how to find this display ?

Could you build large 7-segment displays using ws2811/2812 strips?

I'm interested in a commercial displays more. What I meant of diy project is to get the main parts and assemble them using arduino as the controller with any serial communication method, those commercial duty sensors on Aliexpress and a large display like P1, but I'm interested more in the one at the last image I posted.

Yes, I know you mean something like this one:

Yes, I think building a similar display by myself would be much cheaper than what this display costs.

OK, I found the solution here:

Arduino + P10 Panel + DS1307 | Digital Clock Using LED Matrix P10 with Arduino Uno and DS1307 RTC

I should have searched a bit more before posting this thread but anyway I hope this thread would be handful for anyone that is searching for this project.
