VISION
Nowadays kids are not concerned about the correct use water resources.
The aim of this project is to create an intelligent didactical bathroom in order to educate children so that they become aware of unnecessary waste of water while their Bathroom Eco-Experience.
For achieving this goal, the help of Fluvi is indispensable. Fluvi is going to give advice to the children of how should they have a shower, wash their teeth and their hands in case the parents are not available at the moment. Fluvi will guide the children so that they know step by step what to do to have good hygiene habits.
Nevertheless, the system is also a good and easy way to help the family members to save water and control what is happening in the bathroom.

SPECIFICATIONS
PURPOSE AND SCOPE
The goal of our system is to make the children aware of the importance of taking care of the water in these days that we are facing so much problems with water scarcity.
For achieving this goal, we will teach children how they should have shower, wash their teeth and their hands to reduce the water consumption.
The system consists in a Virtual Educator that shows step by step every activity. There will be sensors in the shower and sink measuring water consumption, water temperature and presence.
With the obtained results the system will guide the child through sound and colourful-light effects for reaching a sustainable behaviour.

Non-Functional requirements
Efficiency
The system acts in real time and waste the exact quantity of water. It also integrated in the bathroom space. The sensing system is basically conformed by presence,flooding and temperature sensors, as they are really simple and well known sensors they should be really efficient.
Usability
The system interacts with the user mainly with voice communication mainly if the user is a child, also with the help of Fluvy images which helps the young person understand better.
Reliability
As the system is basically a tutorial, and the functions made by the sensors are really basic, the reliability of the program is really high, despite the fact of the maintenance of the sensors.
Portability
Portability in our system is not available, as it is design for a specific zone in the house and it should be isolated of water reach so that the circuits and connection does not suffer any damage with humidity.
Sensor
- 5 pressure sensor
- Water consumption sensor
- 2 temperature sensors
- Presence sensor
Actuator
- Set of speakers
- Indicator LEDs
Ethical
The system is adapted to children and could be used for all types of ages. Therefore doesn´t infringe any ethical reflection.
Legislative
The system doesn´t need any personal information to operate and doesn´t have to comply the privacy laws.
ARCHITECTURE
HARDWARE
SYSTEM
Central Server: the Central Server is the brain of the intelligent bathroom. All computation is helded in the mini-computer. The Central Server is connected to all sensor and actuators and defines when to act.
Automatic lights: the regular lightbulbs are substituted by intelligent ones that are conected to the Central Server and they’re turned on and off automatically.
SHOWER
Sensing
Mat pressure sensor: the shower mat will contain a pressure sensor that indicates to the Central Server if someone is standing on it.
Gel and Shampoo sensor: a double pressure sensor below each of the products detects if some of them are removed by the child and communicates to the Central Server.
Temperature and water flow sensor: this is the main sensor of the system, it detects the water flow and temperature and sends the data to the Central Server where computations are made.
Acting
Speaker: there is a waterproof speaker inside the shower, connected to the central server via bluetooth, this will reproduce the shower teacher commands.
LED lightbulb: there is a LED ligthbulb near the shower that indicates shower time to the user via different color lights. (It turns from Green to Red, going through Yellow as the time goes by).
SINK
Sensing
Temperature and water flow sensor: this is the main sensor of the system, it detects the water flow and temperature and sends the data to the Central Server where computations are made.
Soap and toothbrush detector: this sensor detects if the user is getting the soap or the toothbrush to communicate to the central server which of the protocols(teeth or hands) should activate.
Acting
Speaker: there is a waterproof speaker inside the shower, connected to the central server via bluetooth, this will reproduce the sink teacher commands(either toothbrushing or hand washing).
LED lightbulb: there is a LED ligthbulb near the shower that indicates shower time to the user via different color lights. (It turns from Green to Red, going through Yellow as the time goes by).
SOFTWARE
The main program of the system is held on the Central Server:
- ll the data collected by the sensor is sent to the Central Server in order to compute it and generate a response to the different means of communication that the system has with the user(light, voice commands and sounds).
- The main programming language used is Python 3.6.1
- Arduino libraries
- Google Speech API
SHOWER
The system activates the protocol when the pressure sensor placed in the mat detects someone standing on the mat (Se:2). The system asks the user if he is a child and if the answer is positive starts the shower protocol (Se:3). The system is able to track if the child is following its instructions or not (Se:4). In order to know when to notify (In:1) the system control the water comsumption (Se:6).
SINK
It is somehow a simplified version of the shower protocol. In this case in order to initiate the protocol the system detects if the user get’s the toothbrush or presses the soap dispenser (Se:5)
The room lights are connected to a Z-wave movement detector to turn them on and off automaticaly.
The user interaction with the system will be through a web application..
