    If this is the PIR sensor that Parallax sells (www.parallax.com/detail.asp?product_id=555-28027), then it comes with documentation which can be downloaded from the webstore page and includes the information you want. If it's not Parallax's PIR sensor, you'll need to find out who manufactures it and consult their datasheet.
