Abstract
The ultimate purpose of this paper is to develop a remote controlled security door using a microcontroller. It is a means of enforcing security features of the entire building structure, equipped with appropriate management control. In this paper we have designed system that allows unlocking a secure door remotely. The main aim of this paper is to help users improve the door security of sensitive locations, from car parks, shopping centres or corporate head offices to airports, banks or nuclear power plants. This paper takes a cursory look at other security methods of controlling access, their disadvantages and then goes on to the design of the hardware as well as software programming to lock or unlock the door. Both software and hardware for the system were developed in this paper by using microcontrollers, relays, sensors, induction motors and some mechanical system to demonstrate the response of the output and input devices.
