I need hellllllllp

hi

I'm trying to build a circuit for PIR sensor LHI968/RE200B. I don't know where to start can any one help me out with the circuit

Phew, I almost thought you were drowning there or something.
Careful with those subject headings, you'll give a couple people here a heart attack.
Damn.

Have you tried an internet search, or searching the variety of forums available?

How about the PDF file for the sensor itself? I'm certain the best place to start is NOT the ****-chat area of an electronics forum. An LH968/RE200B sounds like neither a ****, or a chat.
