I am Guessing that a PIR to detect carbon based units is an Analog device. Am I correct?
I want Marty to detect carbon based units. I figured since it detects from close to far it would be an analog signal instead of Digital.
"The PIR (Passive Infra-Red) Sensor is a pyroelectric device that detects motion by measuring changes in the infrared (heat) levels emitted by surrounding objects. When motion is detected the PIR Sensor outputs a high signal on its output pin. This logic signal can be read by a microcontroller or used to drive an external load."
PIR Sensor from Parallax, Inc.
PIR Sensor from Radio Shack
*confused*
P.S. do you have a PIR on your robot. Or, does anyone else? Just curious if you could share your script or pix etc.
