Microcontroller Based Bi-directional Vehicle Counter and Automatic Gate Controlling System

Abstract The objective of this paper is to make a controller based model to count number of vehicle in and out of corporate company and data will send to concern person through GSM. In this paper used RFID Reader to detect the presence of a vehicle. According to this, if we place RFID card it worked as in count. Automatically gate will open and close depends on the vehicle presence and if we scan again it counted as down This count value is send SMS through GSM; Depends on the no of count inside the room according to that lights will turn on, when the count in room decreases automatically lights in the room turn off. When the data corresponds to the data on the microcontroller, the load is switched, which is controlled by the relay from the output of the microcontroller. If the correct tag is disabled, the system will display the message “AUTHORIZED”, “UNAUTHORIZED” elsewhere and will not allow access. In addition to LCD screens, bulbs are used as lamps. The project can be further improved by integrating it with GSM technology. Any unauthorized entry can be reported to the security staff via SMS.
