Implementation of a GSM phone-controlled door using a microcontroller

Provision of adequate security system in Nigeria has become one of the major challenges due to the level of insurgency that is increasing at an alarming rate in the country. The need for protection of life and properties therefore requires additional security measures. In this study, we designed and implemented a GSM phone-controlled door using microcontroller. The design was achieved by the use of GSM technology, Atmega 2560 microcontroller, GSM Module, and a keypad. The Microcontroller was programmed using Arduino C language and simulated using Proteus 8.1. The door can be remotely controlled by receiving set of instructions either through the GSM phone or the keypad acting as the transmitter. The modules are made possible using modern integrated circuit chips, ensuring proper conversion of signals to acceptable codes, enabling the microcontroller to communicate properly with the switching device responsible for opening and closing the door. Results show that, the microcontroller accepts input from the keypad in form of password, process it and grants access if the password is correct, or deny access if the password is wrong. However, if a wrong code is sent over three consecutive times; the password will have to be reset, because the system has sensed an intruder attempt. The device can be recommended for use in our homes, offices, business places etc. ensuring a good security system.
