Datasheet for PIR sensor?

[JimInWoodstock]

Do you have a data sheet for the PIR sensor? I am specifically interested in the 2 adjustment pots. What each one does and how to best adjust them.

Hi
I have assembled the latest MotionMote kits and they are not operating correctly.
I think I know the problem....
I note that the latest PIR sensors do not have the same removable jumper clips only solder pads.
Before I start cutting traces and soldering. It looks like the PIR sensors are default set to the H mode -continuous trigger. Should they be L mode -single trigger. Is this the case?
So I need to cut the loop trace to H pad and solder bridge to L pad.
Thanks in advance.

After a bit more research, then snipping and soldering, jumper now set to "L" and all is working fine.

It may need a note in the MotionMote guide to highlight the need to change this for those PIRs without removable jumper and pins.

Regards.

Unfortunately they sometimes come with removable jumpers, sometimes with pads, I can't really control that. The most important part is removing the regulator/diode to allow the sensor to work well below the 4V of the LiPo.
