IoT Smart Bathroom

This project aims to develop a “smart” bathroom making use of relevant capacity utilization data, such as: people flow during a pre-established time interval; facility utilization data (number of visitors versus time they stayed in the bathroom), and, according to the physical space utilization rate, trigger “on demand” cleaning process alert (via Twitter). This kind of technological solution can be applied in areas with intense flow of people, such as hospital hallways, restaurants, museums and similar ones. As result, a better cleaning team dimensioning is expected, which leads to optimization of resources utilization.

Before reading the next steps, make sure that your Intel Edison is configured with the newest firmware.

For this step, you will need:

- 1 Protoboard

- 1 Ultrasonic Sensor HCSR04

- 4 Jumpers

- 1 Intel Edison

- A wi-fi network

Fix the ultrasonic sensor in the protoboard, then connect the jumpers into the right pins (gnd to gnd, 5V to 5V, trig to output and echo to input).

Make sure that the Ultrasonic Sensor is set in front of the bathroom door looking to the door. It has to be able to detect when someone passes between the sensor and the door.

The whole code of the project makes use of Python, so make sure you have installed the following API's:

- Pip Python.

$ opkg install python-pip

- TwitterAPI.

$ pip install 'TwitterAPI' 

You can check the TwitterAPI documentation here:

https://github.com/geduldig/TwitterAPI

Attention: Make sure you have the newest version of the firmware, because you have to use the library "mraa", and it doesn't work with older versions.

Copy this code to the terminal and set a Wi-Fi network:

$ configure_edison --wifi

Find your wi-fi network, write the password and connect your Edison to it.

For this step, you will need a Twitter account.

1. Sign in your Twitter account

2. Enter this link:

https://apps.twitter.com/app/new

3. Input a name, any description, a website url and agree with the terms.

4. Click on "Keys and Acess Tokens"

5. Save the following information: Consumer Key, Consumer Secret, Acces Token Key and Acces Token Secret.

Those steps are necessary and they will be included on this part of the code:

from TwitterAPI import TwitterAPI

TWEET_TEXT = "YOUR TEXT HERE"

CONSUMER_KEY = 'YOUR CONSUMER KEY HERE'
CONSUMER_SECRET = 'YOUR CONSUMER SECRET HERE'
ACCESS_TOKEN_KEY = 'YOUR ACESS TOKEN KEY HERE'
ACCESS_TOKEN_SECRET = 'YOUR ACCESS TOKEN SECRET

api = TwitterAPI(CONSUMER_KEY,CONSUMER_SECRET,ACCESS_TOKEN_KEY,ACCESS_TOKEN_SECRET)

r = api.request('statuses/update', {'status': TWEET_TEXT})

print('SUCCESS' if r.status_code == 200 else 'FAILURE')

A web interface is used to check the status and information given by the SmartBathroom.

Here is the code for ToiletDash.json:
