I have this sensor from a security alarm... i have open it and get the little pir sensor (2030B).
I have readed the pdf about it and i know what are the connectors in it
Question... the pir sensor will work stand alone? i have connected the sensor to arduino 2009 and use some code that shows the sensor response...but i think that is not working because even disconnectiong the sensor the values are the same.
What is needed to the sensor to work? can i make it with my breadboard?
