Need Advice on SENSORS for a project

[Megahertz]

Hi,
For the tilt angle it again depends on the accuarcy and resolution and (but certainly not least) the mechancis to which it's going to be mounted. Perhaps a simple pot might do, or perhaps some sort of encoder ((incremental or absolute) optical, magnetic, capacitive etc), or perhaps an acceleromter will do?

I found this IC - http://www.muratamems.fi/sites/defau...t_8261900a.pdf
sca61tfa1hig - part number which can measure 0-90 degrees.

On page 3, section 1.2, under performance characteristics I can see it says measurement in "+-1 g". I would like to ask:

1) This seems to be measure of acceleration, but I do not see any separate output for measured acceleration on the IC.
2) If I just want to measure the angle lets say after every 250mS or 500mS, - Is this sensor suitable OR measurement of acceleration will be integral to the calculations involved.
3) If acceleration is involved then if lets say the object is stationary at 30 degrees, will this sensor output 0?

Also I read that the sensitivity is 2V/G - Please could you clarify what it means? Thanks
