Implementation and development of smart mobile phone security access system (SmartSAS): article / Wan Ikhsan Wan Ishak

Home security system is very importance for all residents who put safety as a priority in their daily lives. In line with this, a project is developed to construct a security system that is connected via mobile phones when the alarm is activated. The whole project is implemented and developed both hardware and software. This project consists of keypad as the input for password key-in, PIC16F877A microcontroller as a main controller and a DC motor which acts as an output. Once the system is tempered by an intruder, the alarm is activated and the system will notify the user through a mobile phone. This alarm will be deactivated when the correct password is entered. Another feature of this alarm system is that it is equipped with auto lock system when a person enters the premise with a correct password or leaves the house within an allocated time delay (30 seconds). From the analysis, the probability for the intruders to break into the security system are 2^16 since the system is equipped with 6-digit passwords. In software implementation, MPLAB and C program languages are used.
