Looking for a good 3 axis digital gyroscope

gyroscope?

hi all

i need a 3 axis digital gyroscope to be used in my project.........do any one know good product

thanks for help

Re: gyroscope?

Use the search function on this site for the word 'gyroscope' and you will find two good discussions with links to commercial products.

Re: gyroscope?

it depend on precision. anallog devices make some kind of MEMS gyros, one japan company make it with piezo crystal, there is also with optical fiber....

Re: gyroscope?

Links in this forum direct you to inclinometers (tilt sensors).
This is ease to built: dual-axis accelerometer will give you nice tilt sensor (on the web there will be plenty of application notes on AD-series of accelerometers, and because some of them are used in cars as triggers for air-bags they are not very expensive)

Orientation: are you trying to built yourself electronic compass?
First have a look at the Advanced Orientation Systems web page. There they advertise EZ-Compass, which is tilt and temperature compensated.
This will give you an idea what to expect out of it..
Next you can find in August 97 eddition of ElectronicsWorld & WirelessWorld an article on electronic compass by B. Speake called SCL004. That thing looks like a PIC micro with external EEProm + magnetic sensor.
The PIC operates through RS-232 interface sending out orientation in degs.
This KIT was delivered with reasonably good description on theory and on the device itself.
I think this will be very solid starting point..

Re: gyroscope?

Three gyros in X, Y, Z axis?

are u developing some missile or what.

any way u will have to use three gyros mountind in the specific three directions.

no of course.......... 8O
it is an rc plane

will can i use 2 gyros...one of x-y coordinates..........and the other is a single axix may by the x-axix which i put in the verticle axix to work as it is a z axix ?

Yes in the verticle axis
