Development door lock system via bluetooth using 8051 microcontroller

Abstract

Bluetooth is a wireless communications system that intended to replace the cables. Bluetooth profiles definitions of possible applications and specify general behaviors that Bluetooth enabled devices use to communicate with other Bluetooth devices. Unlike infrared signals commonly used by older remotes, within the suggested range, the Bluetooth device can be used directly in front of the device connected. However, due to the development of Bluetooth spreading fast following the track of world globalization which brings most of the advantages to the users. Bluetooth usage among the world community led the project control door lock system via Bluetooth is carried out. With the knowledge of Bluetooth and also the concept of electronic review this project will uses for the community and also use in the industrial sector. For this project Bluetooth is useful since its helps the user to control the locking of door on an estimated suitable distance. By having this kind of technologies its provide easy lifestyle for the user. The door lock system consist of own made 8051 microcontroller circuit which is connected with the relay circuit that used the electromagnetic lock as the output of the circuit.
