Microcontroller-based room access control system with professor attendance monitoring using fingerprint biometrics technology with backup keypad access system

The conventional way of opening a room was used in the classrooms and laboratory rooms of the Colegio de San Juan de Letran Engineering building, wherein the doors were unlocked using the key for each doorknob in the building. The switching of lights and air-conditioning units were also manual and time consuming. The researchers constructed a prototype focused on automating the access of the room and the control of the utilities such as the lights and the air-conditioning units. Biometrics system specifically; finger print, with a backup code was the main access keys for the automation. The attendance log and the access information will be stored in a SD card and it would serve as the database of the system The design project with a secured biometric access system aims to lessen the time wasted on waiting for the personnel-in-charge in opening the room and the overstaying of the proffers in a certain class. This also monitored the attendance of the professors per class.
