Security Sensor Shield

[nitram]

I have not been able to find any discussion on the above shield so I hope this is the right place to post. My question is where do I source the PIR sensor used in the shield quick start guide on the Freetronics web site and in the Practical Arduino book in the chapter "Security/Automation Sensors". I have searched online and can find plenty with two and three wires but none with the six terminals as shown in the guides.

Thanks for the quick reply, have now ordered a couple to play around with.
