Slide 1 & 2
Introduction
Slide 3
Introduction to sensors
The sensor is a device which detects and responds, sensors work like the human senses
Slide 4
Smoke/gas sensor
It’s a sensor which detect smoke or gas and then sends signals for an alarm to start (example)
Slide 5
Motion sensor
It’s a sensor which detect the motion or anybody which cross its range
Slide 6
Light sensor
How it’s work? : whenever there is a light dropping on the sensor the led won’t light, but if it’s dark your led will light up (if your circuit is connected in the right way)
Slide 7
Ultrasonic sensor
How it’s work? : that sensor sends ultrasonic sensor and receive it back, so you can use it to know the distance between you and an object which later you could use an alarm as an additional option to your project
Slide 8
Activity
Slide 9
As we said last session, we solve problems with two ways which are obvious and systematic
Slide 10
It was a recap on the last session and intro to our next part of the session
Slide 11
DEFINE THE PROBLEM one of the most important steps while you are solving any problem or process. We use 6 questions which we called them (5W & 1H)
Those 6 question aren’t fixed but they should begin with (what/ who/where/when/why/how)
Slide 12 & 13
Those slides where one of the important slides on that session. As we TechSolvers were made to solve and create. Those were some techniques to solve some problems but there’s much more solution techniques you could think of them by yourself.
Slide 14
After thinking of more than a solution to your problem you have to CHOOSE one of them to apply, but which one would you choose and why will you choose it?
Firstly to get less options but better you should eliminate some of your answers which they will be obvious as no one can do that answer (illogical)
Secondly start to compare between your answer using an evaluation matrix, it’s a matrix which you put all of your solution and also your conditions (COST, TIME, MAN POWER, ETC…) until you find the solution which suites your case perfectly
Slide 15
We are human, we all make mistakes and not always our evaluation or calculation is right, that’s why this step is there you start to try your solution it should work but if not you have to go back to your matrix and take the 2nd best solution and so on.
Slide 16
Analyze and feedback to your solution to check is it stable? Do I need to change that solution after a while? Will this problem happen again? Why didn’t we do that solution before the problem? And so on …
Slide 17
Recap on the above
