There are 2 PCB's visible in your pictures.
The second PCB, which is only visible in the 3rd. picture might have a relay (relais) on the invisible side.
You can probably alter the PCB so that that relay will not be connected to the 230 volts DC  anymore.
Then you can use those contacts to switch your Arduino.
This still will require you to power the PIR sensor from 230 V, and i'm hesitating to advise you to do so (because you have to ask this question).

Having for the moment no alternative, is there a risk if I branch (fiddling) sensor on my arduino board via the 3-wire without using external power?

Oh ok, I note that !
There is same part of the composant name erased on the 2 transistor (I think, but I'm not sure, that they are same)... I could be "S9...14" or "SW14" or "S9914". It realy difficult to read, even with wen.

I forgot to say to you that there is written "rs8w2" on the 2 PCB.

I surrounded colored parts of the circuit which was connected to the wire color surrounded:

Chip:
OM3
HA17324

Is this a transistor :
If yes, I'm not sure but it must be:
S9994

Thanks for answers  smiley
I do not know how to put ... Here are two new photos of the PCB. If it still need a better quality I'll go get my camera.

Dès que quelqu'un passait devant, le projecteur s'allumait. Le model, c'est "RP500" 230V 50Hz ; MAX 500W.

Hello !
I'm not very good at electronic and I need you to help me. I got a projector on which I disassemble the proximity sensor for the purpose of my project home alarm.
Here are the pictures of the sensors in question:





Can you tell me how I should manage to connect on my Arduino? Must I use an adoptator or anything to connect on sector ? In the best case, it is possible to connect directly to the card?
Note: The color code my threads is that of France (I do not know if that changes anything).

Finally, I joined 3, 7 & 10 on one pin and it works (it is only after had the idea that I understood your post...) ! Thank you  smiley

Thank you for your answers. Unfortunately I can programmed only during the weekend, so I'll keep this post neighbor. See you soon!

Up please !

That's what I do :
Quote
const byte ROWS = 5; //four rows
const byte COLS = 3; //three columns
char keys[ROWS][COLS] = {
  {'3','2','1'},
  {'6','5','4'},
  {'9','8','7'},
  {'#','0','*'},
  {'B','R','W'}
};
byte rowPins[ROWS] = {0, 4, 6, 8, 9}; //connect to the row pinouts of the keypad
byte colPins[COLS] = {11, 3, 5}; //connect to the column pinouts of the keypad
It works well for all the key exept for "8,0,R")

Here my keypad:

I know this tutorial but my keybord looks differents. It don't run in rows and column (but perhaps I'm wrong about the operation of the keyboard used for explanation).

It not this phone keyboard but it looks like:

If you really need a photography of mine, I'll give you.



Redit :
I was wrong, it lacked a pin :


Now someone has an idea?
42  Using Arduino / Programming Questions / Phone keypad a bit special on: January 13, 2013, 08:59:47 am
Hello !
I currently generates code. I retrieve a keyboard phone.
Here's how it seems to work (15 keys). I tested each key pin by pin:


If I press a key, I look on this array where is 2 "1".
Exemple :
I press "M" (bottom left), the circuit is closed between pin 1 and 2.

How can I use the Keypad library to run this keypad ?

Thanks for your help and sorry if I make mistake, my native language is French smiley-wink

I return to inform those who have the same problem as me. Processing encounter compatibility issues with Windows 8.
I went back to Linux, I'm waiting for uptades.
Good luck !

I will try on XP, I go back in a few minutes smiley-wink
45  Using Arduino / Interfacing w/ Software on the Computer / I can't load Arduinoscope on: January 06, 2013, 02:08:33 pm
Hello,
I try to use the open projet "Arduinoscope" but I have a lot of problem.

My configuration:
- Windows 8
- Arduino Uno (with arduino-arduinoscope.pde)
- other information on the screen...

I take a screen (it easier  smiley-lol ) of the emplacement of Processing and the arduinoscope library folders, and also what I see when I try to load the scope.


Error message

Thanks smiley
