PIR motion sensor

I have a instruction in a book (Programming Interactivity) of how to connect a PIR motion sensor.

I only don't know if the book has the same, i would think red would be +, black gnd, and brown to detect the input value. Only the book has another idea.
I can only read: hkp and under that: 093 for the rest the plastic is over it.

Also can i damage my arduino when i do it wrong?

I got it from freeduino.cc only they closed there webshop.
Neither i got a datasheet.

This is from the book,

also with the datasheet, is the PIR seen from top or bottom? Cause relays have connections at the bottom for example so there could be some logic in having things rotated 180 on datasheets, it could also be logic that it is not.

This looks very much like your sensor at Sparkfun PIR Motion Sensor (JST) - SEN-13285 - SparkFun Electronics and they have a datasheet.

Somewhat unexpectedly, the site says this:

Red wire is power (5 to 12V). Brown wire is GND. Black wire is open collector Alarm.

Thanks, i will try that.

also, sometimes you can do things muttiple ways, but is it me or is this kinda strange:

is this kinda strange

Looks fine to me - what's bothering you about it?

that the digital pin, pin 2 is connected to the 5v.

anyway,
found out i could remove the plastic to take a better look at the number, found out i have:

I hope i didn't damage it cause i had the wiring wrong one time.
It runs at 12v so that is the next problem but i can probably find somewhere on the forum of how to do that.
