Gsm Based Door Lock And Unlock System

DOWNLOAD ABSTRACT

AIM:

Design and development of GSM based Door Lock and Unlock System using Arduino.

PURPOSE:

In today world security is primary concern for homes, offices, laboratories and industries. Everyone can access normal doors in these premises. We have some security systems for door access like RFID, Smart Card, and Finger print…etc. But all these are static and if one has access then they can access in any time. Here we propose GSM based door lock and unlock system. Using this main admin can access door from remote location at any point of time.

DESCRIPTION:

This project includes GSM (Sim800C) module, which is connected to Arduino through UART interface. Dc motor Controlled by Arduino through L293d. When DC motor rotates in clock wise then door will be Close. When DC motor rotates in anti click wise then door will be Open.

WORKING:

When User sends lock command from mobile SMS then Door will be Close. When user sends unlock command from mobile SMS then door will be Open. User can get Door status by sending request SMS to Arduino. Door status information will be displayed on LCD.
