This paper discusses the design and implementation of a GSM based digital door lock security system using Raspberry pi controller platform. A 4-digit password was used to lock/unlock the doors by employing a stepper motor. Three consecutive unsuccessful attempts in entering the correct password results in sending a warning message, was sent to preset mobile numbers, as a means of detecting unauthorized intrusion. A 3D scaled model of a house with door controlled by a stepper motor was constructed to implement and demonstrate the proposed system. A separate arrangement was made to install the control. The experimental result and analysis were promising. The proposed system developed based on Raspberry pi micro controllers.
