All,
Has anyone any real world experience with the freescale 5010 sensors. Got one hooked up today to write some software for and what I see is the pressure dropping over time.
This of course would suggest a leak of course. I can confirm I don't have a leak
Hooked it up with / without bubbler / with / without non-return valves. Appears to drop 0.01v every 30 seconds or so until it pretty much hits atmosphere (around 0.08v) . My voltmeter is not the best, but the arduino shows the same so not worried about the exact voltages, more the unexpected change.
I have tried a couple of sensors, different tube.
All the ones I see on the net have a stable reading, why is mine out ?
Any suggestions ?
