I need to measure inclination ( high accuracy)

Joe

Hi,


I read some of the Parallax pdf about sensors.

But I can't find resolution of inclination.
( For me it isn't necessary 8g , only 2g is good but I need accuracy )

Do you know which is the best sensor to measure inclination
and which is the accuracy of it.

Thanks, Joe

What is your price range? There are devices that will measure in tenths or hundredths of a dregee for a price but if you are looking at hobby equipment you might get a degree resolution. Also best is subjective so if you can explain in what environment and what accuracy you need.

Stephen,
Could you use three hobby sensors and average the value and get a much more accurate reading?

Hi,


I want to use Parallax products for this purpose.

Do you know how can I have better accuracy , more than one grade accuracy ?

I just need to measure from 0º to 15º only but less than one grade
of accuracy . 0,5º accuracy or 0,025º could be good for me.

Any idea ?

Thanks.

Probably. You would need at least two I would think to account for tilt in the axis. It all depends on the sensor. Some of the new MEMS products are quite good.

Joe,
did you check out the nuts and volts article on the parallax memsic 2125 page?

http://www.parallax.com/Portals/0/Downloads/docs/cols/nv/vol3/col/nv92.pdf

See page 7, it shows the accuracy of tilt down to 1/100th of a degree in the sample code listed.
