Security Sensor Shield
Posted: Thu Mar 27, 2014 2:47 am
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.
