Room access monitoring system

This paper presents a room access monitoring system, which integrates computer and microcontroller MOTOROLA MC68HC11A8. Assembly language is used to program the microcontroller and Visual Basic 6 (VB) is used to develop the monitoring system. The monitoring system is divided into server side program (Eyewatch) and client side program. The server side program informs the user about the door status through the client side program. The purpose to develop client side program is to enable user far apart from the door, know the status whether the door is block or not. The microcontroller is integrated with a keypad and LCD display. Only an authorized person can enter the room. If an unauthorized person trying to break through the door, an alarm will be activated.
