Looking thru all my archives....can't seem to find it....but some time ago (year maybe) someone had posted some info on inexpensive but good PIR sensors.  Anyone recall that reference?

What sort of range are you looking for?

Also, not sure what your app is -- but you can "dead bug" a commerical PIR
from Home Depot etc.

Alan,

PIR sensors.  Anyone recall that reference

I don't, but you can try some of these links.  The sensor interface is
relatively simple; basically just an amp and a low pass filter.

I just noticed that http://www.allelectronics.com is carrying a Nicera
detector (catalog# IRD-10) for $3.95.

You could also try http://www.mpja.com. When I last looked, they
carried both the RE200B part as well as a module with lens
for about $10.00.  You will probably want the lens as well as the part.

Try here too

I've used the attached circuit with Murata sensors. Uses a few 10s
of uA. Its V+ is a PIC pin

I've used Napion IR sensors with great success :-

There are analogue/digital versions. Dig is better imo 'coz you don't have to
fuss with compartors etc & they lend themselves better to pulse counting if
needed.
