I Am Guessing That A Pir To Detect Carbon Based Units Is An Analog Device.

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.

I have this one but I have not hooked it up yet. It appears to be a digital 5v logic out. I'll let you know soon as I try it out.

"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."

If it is digital, but can be read by an ADC port ez-b, using the command adc_wait, I like it because it leaves more free ports to use digital servos or sensors ping.

That is what I was thinking. This may be one for D.J. to Answer.

So, is it Analog? or is it Digital?

The PIR sensor is digital (Communication: Single bit high / low output), but can be read from a digital port ez-b or from an analog port and using the command adc_wait can chain reaction in your robot as if a switch connected to a digital port, I hope I have cleared your doubt MovieMaker.;)

thanks, R2:D

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.

I have no pir sensor mounted on the robot, the truth is that I have reserved for the RSP robot, but when you install certain to be published.
