Sometimes tilt sensors are incorrectly called inclinometers because the sensors simply generate a signal (as opposed to inclinometers that generate a reading and a signal). A basic circuit using a tilt sensor is shown here. For this assembly, the components used are: a tilt sensor, a 470 Ohms resistor, a LED and a 3V power supply.
An inclinometer or clinometer is an instrument used for measuring angles of slope, elevation, or depression of an object with respect to gravity's direction. It is also known as a tilt indicator, tilt sensor, tilt meter, slope alert, slope gauge, gradient meter, gradiometer, level gauge, level meter, declinometer, and pitch & roll indicator.
Image showing the face of a turn coordinator during a standard rate coordinated right turn. The turn coordinator (TC) is a further development of the turn and slip indicator (T/S) with the major difference being the display and the axis upon which the gimbal is mounted. The display is that of a miniature airplane as seen from behind.
Tiltmeters may be purely mechanical or incorporate vibrating-wire or electrolytic sensors for electronic measurement. A sensitive instrument can detect changes of as little as one arc second. Tiltmeters have a long, diverse history, somewhat parallel to the history of the seismometer. The very first tiltmeter was a long-length stationary pendulum.

Liquid capacitive inclinometers are inclinometers (or clinometers) whose sensing elements are made with a liquid-filled differential capacitor; they sense the local direction of acceleration due to gravity (or movement). [1] A capacitive inclinometer has a disc-like cavity that is partly filled with a dielectric liquid.
Tilt sensors (in their practical use) are significantly different from inclinometers: the term "tilt sensor" is used for a dynamic measurement, often as a qualitative user interface control, whereas inclinometers are quantitative, calibrated and rely on some stability.

There are several different basic designs (tilt, displacement, radial, etc.) but they all share the common design strength of non-eroding switch contacts. The most common is the mercury tilt switch. It is in one state (open or closed) when tilted one direction with respect to horizontal, and the other state when tilted the other direction.
