I'm looking for a way to measure angle/inclination (on one axis) in a
dynamic environment, (as on a moving vehicle, or plane etc).
I tried to put toghether a gyroscope/accelerometer board but I ran into
calibration issues so I bought one from "Rotomotion.com" but now I need to
find out how to apply a kalman filter to the outpout so that I can get the
combination of the two signals in order to get an actual angle or tilt
reading.
I'm going to try and list all the parameters:
1. Output should be a voltage variation (preferably between 0v-10v), for a
range of 0 to 90 degrees directly proportional with the actual inclination,
for example if I get an output of 1v the inclination would be aprox 9
degrees, 5v=45 degrees, 10v = 90 degrees etc.
2. The device will be mounted on a moving vehicle that is able to pull high
g's in all three axis so I have to account for the error that will be
brought on by the acceleration factor
3. There will be some metal components various temperatures and of course
electric and magnetic interference, (motor, wind, etc). I can try to shield
against that but I would have to know the magnitude of the effect that these
external variations have on the measurement so that I can compensate for it
with an adequate shield.
4. The sampling speed of the device should be around 100Hz and the accuracy
should be in the area of about 5 degrees.
Any help such as schematics, components, or ideas on how to proceed would be
greatly appreciated
Also if any one knows of such a device with similar characteristics that I
can probably modify please let me know
I'm trying to keep the cost between $80.00 to $100.00
