Introduction

Statement of Purpose

In some of the university housing, in my case, FAR, residents on the same floor share six showing rooms. Usually there is a good chance where there is no showering room left, so in such scenario the guy who is in bad luck have to go back to his room and wait an arbitrary amount of time and go check again. The project is to design a notification system which will have a display in the corridor so that residents don’t have to go in and check if there are spare rooms to shower.

       Background Research

Here is the floor layout of FAR-Trelease floor 12[1]


In the blue square is the six showering rooms, and the red square is the proposed location to put the display. It is verified that with the display in the red area all residents are able to see it at their door.

It is possible to detect whether the room is in use by the status of the lock, and can be done with a hall sensor or a flex sensor.

It is possible to transmit data through wireless technology from the sensor to the display, at the range given in the layout graph.

There is already some similar application of this idea, such as on the airplane, there are corridor lights which indicates the status of the restroom. This project is different form the one mentioned above that this project is going to have six different inputs and one output.

Design Details

System Overview

All sensors are connected to an Arduino, and the Arduino is connected to a wireless transmitter, possibly Bluetooth.

The display in the corridor is connected to an Arduino which controls what is displayed, and with a wireless receiver, possibly Bluetooth.

Parts (tentative)

       Hall sensor

       Arduino Uno

       LED Segment Displays

       Bluetooth module for Arduino

Possible Challenges

       Group members have no previous Arduino programming experience

       Powering of each device

       High humidity

Remember the project proposal is due tonight. If you all have made a new page, let me know so we can delete this one.

I think you'll find that is hard to coordinate that many wireless devices. If you would like to go wireless, look into using ESP8266 (or the newer versions) that have built in wifi. I would recommend reconsidering the structure of your project a little (perhaps have 6 sensors that go through some logic, which is then fed into 1 arduino/esp8266 that talks to the receiver, rather than 6 wireless connected devices). Brainstorm a little, and update your project proposal please.
