Motion sensing and image capturing based smart door system on android platform

A smart door system which can be controlled by the android application installed on smart phone is proposed in this paper. Earlier, smart locks were used which enhanced the security features of the house. The proposed model can eliminate the concept of lock system as here the security is provided to the door itself. This would result in a safe and secure door with no locks! Controlling the movement of the door is enabled by Raspberry pi and its related embedded software. Also merging IOT with android is has many advantages in terms of security. The motion sensors are used to detect any movement in front of the door. If any person comes in front of the door, a motion is triggered; the image is captured and notified to the owner. Thus in overall proposed system, two technologies are concentrated on, one is motion sensing in the front of the door in real time even if there is no one at home and the second is to control the movement of the door by the smart phone. Thus by connecting a mobile phone to a door, the owner get notified whenever any visitor visits his home and looking up to the images, the owner of the home can send the open door signal for only the trusted visitors.
