Tilt Sensing Circuit
(OP)
Tilt Sensing Circuit. I am looking to build a small, battery powered tilt sensing circuit-on a small board-that can detect when the object it is mounted to deviates by some set limit off of vertical. I have built a crude prototype with a mercury switch built it is much to bulky and "stone age" looking. I am envisioning an accelerometer whose output can be compared to varying limits (set by potentiometers?). When the degree of tilt exceeds the preset limit, a light or buzzer, etc. is powered. Any ideas out there?

Is it rough like +/- 5 degrees, or is it ultra sensitive like seconds of arc ?

This is rough measurement, large angles ~45+/-. It is intended for use in keeping an obeject within set limits about one axis while it is rotating slowly around a secons axis. The rotation about the second axis is the problem I had with the mercury switch. I had read that accelerometers have been used in the automotive industry to sense tilt successfully. I am interested in making a small, light, portable, battery operated device for my application. All ideas welcome!

Mount two such units at right angles and with a bit of computation you can calculate the two dimensional tilt.
Put it all in a bucket of oil if you want to damp it.
Have fun.
