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....
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..
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 ?
