Article Title: Development of Controlled Alert System for Human Access into Premises
by Daniyan, I. A., Daniyan, O. L., Adeodu, A. O.,Ojaokomo, F. and Mpofu, K.

In this present day when armed robbery has gotten more sophisticated particularly in developing countries, there is the need for a more proactive and efficient security measure, and one of the most secured technologies that can be employed is biometrics via finger print door lock. This study deals with the development of controlled alert system for human access into premises. The software that drives the microcontroller was done using the C language on MPLAB compiler, the coding was segmented into two modules; first, the module that drives the LCD screen, next is the module that drives the finger print scanner, this instructs the scanner to first register users and allow the inputted finger print to be compared with the pre-registered finger prints. The pre-registered finger prints are saved on the IC registers of the Micro controller. An alert is sounded whenever a fingerprint that is not found in the Microcontroller memory is placed on the scanner as an intruder. The construction of this project was done in three different stages, the writing of the code (driver) which controls the Microcontroller using C language, the implementation of the whole project on a solder-less experiment board, the soldering of the circuits on Vero-boards and the coupling of the entire project to the casing. The implementation of this work was done on the breadboard as a prototype with the power supply was first derived from a bench power supply in the electronics laboratory. The mechanism can be implemented in a broader sense on a door where there is restriction of access. The successful completion of this work provides efficient security measure which can reduce the rate of armed robbery, kidnapping, theft and unwanted access in premises.
