s sequence is given to the up-count sequence detector, which generates a high output only if the correct sequence has been detected. Similarly, when the car leaves the parking area, it generates a fixed sequence, which is given to the down- count sequence detector. The down count sequence detector generates a high output only if the correct sequence is produced by the exiting car. The outputs of the up count and down count blocks are given to the display section. The display section has a counter and a 7-segment display along with its driver IC to display the count. Depending on the sequence d..................[:=> Show Contents <=:]

sed a light depending resistor in which resistance varies when a person cross by. The LDR get activate when the light gets cut. Two sensors are applied in which the sensor I is used to open the door and to count. And sensor II is used to close the door. Their output is leading to control unit.
CONTROL UNIT
Control Unit consists of an S-R flip flop in which the voltage from the sensors is fed to set, reset pins. One of the outputs is fed to open the door and the other is fed to counter.
COUNTER
Here we use down counter in which when a person is entered the count is decrement..................[:=> Show Contents <=:]
