There actually aren't many other parts needed with the AD595. It's quite easy to set one up on a proto board (make sure you get the 595 in proto friendly DIP package!) with a handful of R's and C's. The datasheet (Google it...) for the AD595 is quite helpful. They get a bit carried away with optimising things for accuracy but if you don't need +/- 1 degree readings then you don't need to bother too much with that level of detail.

So bottom line = not that hard.

Wired it up. Works fine (displaying volts in NT, on a table). Only draw back is it's 3.3v output so the resolution isn't as good as it should be.

Now to make some G-Force csv files.

Nice work - so it's just got an analog output for each axis then??

Yep.



Pretty straightforward (which is good because I have NFI about these things ).
More details about the module here

Awesome! Looks nice and friendly. Friendly = good!

so who is actually using this differential boost sensor ( MPX4250DP ) as mentioned in the 1st post?

does it work fine if you only use one hose input while it still being differential?
i guess 10psi - 0psi = 10psi , i had my doubts just trying to make sure its the right one that works

thanks

I've only used the regular one mentioned in the top of the post. You can still get them

PL mentions the MPX4250GP, which is sold out and no longer manufactured as stated in my 1st link if you scroll down the page.
where would i get the one you mentioned ?

closest is the MPX4250AP but is 3psi-36psi range so pretty useless, 0psi - 36psi being perfect
i'm half temped to get the differential boost sensor and give it a try to see if it works with with only one input hose connected, if it works could set up a 2nd dp sensor hook up the 2nd input before the intercooler just to log boost drop in different intercoolers i guess

Arrow electronics sell them. I did a search ordered two Sep last year:

2 MPX4250GP NXP SEMICONDUCTORS 14.6700 29.34 (AUD)

perfect, just what i was after
just ordered 2 at $106 aud, in total not sure if trade account or prices jumped in the last year, not complaining just happy i got the right sensor

i would have thought this was an essential thread, do you think we could get a new pinned thread like this one on datalogging with updated links when time permits ?
