Done by Group : Doppler School Name : Umm Hakeem Independent Secondary School for Girls. Smart Sensors Module : Gives knowledge about smart sensors and the PVDF films through activities, experiments and projects which depend on smart sensors. the product Idea is : Lightening way which has a sensor in the ground connected to a smart card or a bracelet that have numbers to the destination, by knowing the destination in the information card and by clicking the button in any of smart card or an electronic bracelet a small light comes from the tiny bulbs will show the user his way easily

I am Discovering Materials- cycle 9
Smart Sensors

2. Outline

3. Smart Sensors
A sensor that includes a microprocessor that condition
the signal before transmission to the control network. It
filters out unwanted noise and compensates for errors
before sending the data. Some sensors can be custom
programmed to produce alerts on their own when critical
limits are reached

4. Activity (1): Evading Motion Detection
Results :
Extent to the objects that hit the sensors in 16 ft.
Field in Cone shape
Insulators that prevent sound was:
-Plastic
Ps;
Moving slowly a way to insulate the sound
• Purpose: To know the barriers that are working and which aren’t working
in Ultra sensor
Steps:
1- opening the sensor
2- finding out the area of the sensor cover
3- trying different materials in sensor range

Activity (2): Taking a tour of some sensor
Detecting energy and show their impact in another card.
knowing that the sensors are located in more than one form.

6. Activity (3): Making a Microphone
PVDF is a special plastic material in the fluoropolymer ; it is used generally in
applications requiring the highest purity,
strength, and resistance to solvents, acids, bases and heat and low smoke
generation during a fire event.

Flexible PVDF is more sensitive than Rigid
(Rigid is better in flicked ) - ( Flexible is better in others)

8. Activity (4): Exploring the Piezo effect
Part A) Building the PVDF monomer
- Which is C2H2F2
Steps :
1- insulate polymer step
2- putting monomers together

9. part B) Building the PVDF polymer

10. Activity (5): Measuring piezoelectric or pyroelectric
response
•Piezoelectricity
The word piezoelectricity means electricity resulting from pressure.
•Pyroelectricity
Is the ability of certain materials to generate a temporary voltage when they
are heated or cooled.

11. Results :
Discover that flick on the subject will :
1- Give Voltage
2- Appears a chart on the laptop to show the result or

13. Lightening Way
According to Qatar 2030 vision and based on holding the world
cup in our country, this project will be very useful for tourists,
visitors, inhabitants and also citizens.
This project will be found in public places to show their
technological development. It also will help all the fields.
Our project will be found in some places such as:
1- Hospitals 2- Centers
3- Universities 4- Airports
5- Association 6- Libraries
7- Hotels 8- cinemas
9- Airplanes 10- Football Stadium

14. This project indicate how Qatar is a major
in technology field and inventions.
it’s also worthy to mention that Qatar is
interested in scientific inventions and applying them in life.
It’s noticeable that project will be useful for all categories in the society such
as young people, old people, deaf people and all who can’t read.
Guide students to their classes halls in
University.
Guide the passengers to their gates at the
airports
Guide the visitors to the patients room in
hospitals.
Guide people to the books on the shelves
Guide people to the products in the markets

15. Hypothesis:
• Reduce labor costs and reduce the cost of companies
• A part of safety and security
• It will direct people to their destination quickly
• It will be more accurate for people
• It may count the numbers of people who are visiting
as example
• It will be appear in all of the public places.
• It will have different type of using

16. Lightening Way
Materials :
 Motion sensors
Light bulbs
Electrical Bracelet Electrical Card
Information Card

17. Lightening Way
Uses of materials :
 Motion senior :
connected with the lights and electrical bracelet
or the electrical card to work out.
Light bulbs : shows the way
Electrical Bracelet Electrical Card:
help the user to choose the destination
Information Card : Help the costumer.

18. The sensor will be in the ground connected to a smart
card or a bracelet that have numbers to the destination,
by knowing the destination in the information card and by
clicking the button in any of smart card or an electronic
bracelet a small light comes from the tiny bulbs will show
the user his way easily .
NOTE:
The motion sensor that will turns on
the light may not be only in the ground
It’s even might be at the side of the walls
or at the roof decorated nicely.

Methods :

19. Results:
This Project have a lot of benefits and its will solve a lot of
problems that we found it in our sociality.
Its will save time.
Help people in different ways.
Gives the beauty to the area.
Instruct people to their destination easily.

20. Recommendations:
Since this project will solve a lot of problems which
face people in different places, so we advice to use
the same way of thinking but in other ways.
To add up, we would to investigate for
improvement of the project.
To face the obstacles our advice is to try saving
the used materials, as the used sensors are
limited.
Use the Solar energy
Use some cheep materials

21. Conclusions
Participation in AL-Bairaq project, lets the students workout as a
group team were they lets the student to discover and use new
different type of materials .
To add so, Al-Bairaq may Develop intellectual abilities and also
builds in the spirit of student knowledge and love of exploration
and adventure to undertake and,
also do not forget the spirit of challenge.
