Red Storm
This system wirelessly counts vehicles going in and out of the parking facility and each parking level. This gives the parking lot attendant a regularly updated count on the number of vehicles in the facility at any given time.
There are 2 sensors at the entrance and exit of each level to determine the number of vehicles parked there. When the sensors entering a level are both broken, the LED level status sign decreases by one space and when a vehicle goes through the exit the level status sign increases by one space.
