2. Outline
– Introduction
• Activity (1): Evading motion detection
Activity (2):Taking a tour of some sensors
• Activity (3):Making a microphone
• Activity (4): Exploring the piezo effect
• Activity (5):Measuring piezoelectric or
pyroelectric response
• Design project : Designing a coin counter
• Product Idea: crash savior

3. Introduction:
• A smart sensor is a device
that takes input from the
physical environment and
uses built-in compute
resources to perform
predefined functions upon
detection of specific input
and then process data before
passing it on.

4. Activity
(1)
• Making a
microphone
• Evading motion
detection
• Taking a tour of
some sensors
Activity
(3)
Activity
(2)
In this experiment we
learned the types of
sensors :
We the movement
sensor on the table.
We select the active
area.
We tried to move in
active area without
the sensor detected
us by butting barrier
in front of sensor
In this experiment we
learned the types of
sensors :
We place many devices
with sensors on the
table.
We tried to make
different movement in
front of these sensors.
We observed that every
device has different
sensors which responds
in different way.
In this experiment we
have in several
movements on PVDF
we Attach the PVDF
free film and attached
to a substrate to the
amplifier/speaker
using the connecting
wires. With a flexible
film and rigid film.

5. Activity
(4)
In this experiment
we learned that
PVDF polymer
consists of several
monomers(
C2F2H2)
The experience of
this day is about
determining how
the PVDF film reacts
with bending and
then we fixed the
PVDF on a sponge
piece and threw the
balls in different
sizes to measure the
difference of effort.
Activity
(5)
• Exploring the piezo
effect:
• Measuring piezoelectric
or pyroelectric response:
Design
project
The experience
on that day was
Found the volt
of different sizes
Of coins
• Designing a
coin counter:

6. Final project: crash
savior

7. Hypothesis:
crash savior
Sending panic message and the precise location to the
pre-stored mobile numbers and the nearest ambulance
and police center through common helpline number.

10. crash savior
Benefits:
1-The implementation of this project will
protect the lives of the people of Qatar
3-Inflicting the injured before it
reaches the risk stage
4-The ambulance arrives in faster way
before passengers are at risk
2-It will also reduce the number of facers.

11. Results:
We realized that our project
(crash savior) will save many
peoples life.

12. ØWe recommend that we implement
our project in all vehicles in Qatar

13. In the end , Through our
participation in AL-Bayraq
project, we got many
benefits , namely scientific
culture , especially on
sensors.

14. Acknowledgment
Many thanks to my teachers, school and AL-Bairaq team from
Center for Advanced Materials (CAM), Qatar University for
supporting us during our journey with a AL-Bairaq.
Also, I would like to thank the sponsors UNESCO, Qatar National
Commission.
