3. Smart sensors
A sensor is a device that detects and responds to some type of input from the
physical environment. The specific input could be light, heat, motion, moisture,
pressure, or any one of a great number of other environmental phenomena
Sensors in our life:
- in the gate
- anti-theft sensor
- alarm sensor
- auto parking sensors
4. Activity 1: Evading Motion Detection
Objective: Appreciate the role of scientists in our life.
1- switched on the mini alert motion detection
2- we measured the distance from our hand to the sensor it was 9 feets
3- we recorded the notes
Conclusion: there is thermal sensors and object sensors
-only human movements of normal and high speeds can be detected
Object Motion detection
Normal / High Human speed Detected
Slow Human Speed Undetected
5. Device Input Processor Output
1-learning different types of sensors.
2-Making microphone using PVDF sensor
We knows which sensor it is.
Activity 2: Taking a tour of some sensors
6. Activity 3:Making Microphone
The student should know the importance of
Microphone in our life.
Appriciate the role of scientists in our life.
Teaching as what is PVDF.
Flexible Flexible Rigid Rigid

Flick Less Less More More
Scratch More More Less Less
Blow More More Less Less
Talk More More Less Less
The flexible is better: scratch & blow & talk
7. Activity 4: Exploring the Piezo Effect
-Using atoms and bonds to form monomers and
Monomers can be formed by linking atoms with bond, then
polymers can be formed by linking the resulted monomers.
8. Activity 5: Measuring Piezoelectric
or Pyroelectric Response
Objective: to measure output voltages by
connecting labpro device to PVDF
Large Medium Small
0.9V 0.6V 0.2V
The (Large ball with longest distance)vgives
the highest voltage.
10. Final Project:
Introduction and Rationale:
A car that is driven on its own without the need of a driver. The smart
car can detect obstacles around it in all directions and accordingly
make the appropriate behavior. The car can break and change
directions automatically and can also go straight away if the road is
For even better control, The car is connected to the GPS to know the
maps and location and the best route to the destination.
11. Final Project:
Aim of the work (objectives)
Save the human power that is wasted in driving the cars
The automatic cruise control gives better results than the human cruise
12. Auto driver
Can computer driving be as efficient as human driving?
Will the GPS be able to give the exact directions to the car computer?
Is it safe to have a car without driver running the street?
13. AUTO DRIVER
There is a lot of sensors in the car:
1) There is a sensor in front side from the car.
2) There is a sensor in the back side of the car.
3) There is a sensor right side of the car.
4) There is a sensor lift side of the car.
5) There is a sensor The upper side of the car.
• A system that measure the petrol before destination,
that tells you the petrol is enough to take you to your
destination, and if your trip was longer and the tank of
the petrol could not take you, it tells you that it will take
you to the nearest petrol station.
14. Auto driver
1) This sensor brake the car to It reduces the
speed to not get accident.
2)If there is a car or a truck, it is moving towards
the right or left.
3)Careful not to approach the car or truck.
4)Careful not to approach the car or truck.
5)it check the traffic light and the radar and the

We highly recommend you to take this project into
serious consideration and apply it in real life. We
believe that it will make a great benefit to the society.
We learned so much information about smart sensors
that we didn’t know about before. We also learned
different applications on smart sensors that exist
around us in our daily life.
We were able to come up with a project of our own and
make a full research on it.
AL-Bairaq gave us the chance to get to know science in
an amusing way.
Many thanks to 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, Ras Gas, Maersk and Shell.
