“Imagine a parking lot with 100 parking spaces, what you donowadays is physically check the status(vacant/Busy) of each and every parking space resulting to loss of fuel as well as time. But what if I provide you with a solution in which the status of each and every parking space is visible to you as soon as you enter the parking lot telling you which parking space is free and which is not (like Site 1 is free, Site 83 is Free), plus if the site is free a green led would glow and if not, a red one would.”
