This project was done by the Theory group of Al Shaimaa Independent Secondary School for Girls. The students undergo workshops on the module smart sensors where they gain knowledge about smart sensors and the PVDF films through activities, experiments and projects which depend on smart sensors. At the end students do a design project that challenges them to build a coin-countering device or to invent a new smart sensors of their own. The product idea illustrates the usage of smart sensors to identify the no. of vacant seats in the stadium

3. Introduction
smart sensor:
A sensor that includes a microprocessor that conditions
the signals 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:
Objectives:
1- Understand the function of the smart sensors out of various
experiences.
2- Know the input and the output of sensor.
Producer:
We knew how to
turn on the
sensor.
We measured the
distance that
sensor can sense it.
We knew that
some substance
are touching and
non touching.

5. Result:
1- The sensor input is any movement and the output is
the ringing.
2- The distance that sensor can measure it is 14.25 feet.
14.25 feet

6. Producer:
Objective:
Determine the inputs and outputs of various sensors

7. Input: Touching or Sound

10. Objective:
Build the PVDF polymer.
Result :
The PVDF is a polymer C2H2F2
Producer:

11. Objective:
Observe the voltage produces by the PVDF
film.
Procedure:
1- Connect the PVDF to the Lap
pro to the laptop.
2- Observe the voltage produced

12. Results:
The harder the flick, the
more voltage produced.

16. Introduction :

17. Objectives:
1- Make stadiums developed and facility.
2- In world cup 2022 there will massive
numbers of people who need this idea to
be organized.

18. Hypothesis:
1- If someone set on the
chair, the light will turn
red and if its available
the light will turn green
2- The sensor is here in
Qatar and its available.
3- The world cup 2022
will happen so it will be
a good idea, because
the stadiums will
expand.

19. Methods:
The chair turn green
when nobody set on
it. When someone
come to set it turns
red. So when you
search a chair for
you, you just look
where's the chair that
have green light to sit
on it.

20. Materials:

21. Recommendations:
1- Provide chairs for children, VIP and disabled
persons.
2- Provide light for children like star shape.

23. Conclusion
Finally, after all these activities and lessons, we
learned and profit so much from Al-Bairaq. We
gained a lot of information that we didn’t know it.
Al-Bairaq gave us to think about idea that we can
do it through smart sensors . It opened our minds
and gave us suggestions for that. It was a great
chance for us.
