Pressure Sensor

Post by Don » Thu Oct 09, 2014 12:12 pm

Hi,

What connections must be made to the MPXV differential pressure sensors (Analog Output)? Which pins (if any) can (must?) be left unconnected?

Thanks, Don

Don,

You've probably figured this out long ago. (Sorry about the really slow reply)
There are only three lines on the pressure sensor GND +V (5V) and the Vout line. The other pins are more for mechanical stability and all the pins are in parallel. If you use a meter on continuity you can confirm that.

Hope that helps,

Paul

Yes it does, thanks. The pins are labelled clearly enough. I was just being cautious with the extra pins--didn't want to ruin my sensor. However I did go ahead and try it and it works fine.
