About the project:
Our project aims to give a new way to open secured doors in
public places (e.g. a lab at the University). Our device controls
the electric lock of an intercom door and with an android app it
allows you to send a command to open the door from anywhere
(username and password required).
The project components are
- A Raspberry Pi
- An Android phone
- An intercom door
- A relay
We wrote a server code to run on the raspberry on startup. The
server can receive a request to open the door via WIFI. We placed
the raspberry above the door and connected the door to the raspberry
using the raspberry’s GPIO and a relay, while keeping the existing
tag identifier system alive (Sketch of the electric system available
here). We then wrote an Android app that can send a request to the
server to open the door. The server allows access only when given a
predefined username and password.
Future opportunities for development:
It is possible to send a request to open the door from any
chosen device to the server. The door could be open with our android
app, or with:
- An NFC chip that can replace the tag identifier at the
- A camera with face recognition � using already existing lab
- A secret puzzle pattern constructed via MYO armband and
identified if completed correctly by a drone carrying a camera that
also carries a commercial for Coca Cola.
Relevant files and code:
- Server code.
- Raspberry pi GPIO’s command code.
- The Android app project files.
- The Android APK (KitKat 4.4 and up).
- The door’s electric system sketch.
