I am trying to run a PIR Sensor over 25ft of solid core wire to my Arduino but I seem to be getting a lot of signal interference. I read somewhere that the maximum distance from the Arduino the PIR Sensor can be is 1-2 meters. Is this true?
I have tried connecting the PIR Sensor to the board and it worked. In addition, with only a 6 inch wire, the PIR Sensor works as well. It's just when the longer cable is connected. Is there a maximum PIR distance from the board, or do I need to do something to shield the wire or something to lower the "noise".
Thanks a lot, Lane
