Accelerometers in Electronics
An accelerometer is a device that measures non-gravitational accelerations. These are accelerations produced by mechanically accelerating the accelerometer via its casing. Accelerometers can be used to measure vehicle acceleration.
Accelerometers can be used to measure vibration on cars, machines, buildings, process control systems and safety installations. They can also be used to measure seismic activity, inclination, machine vibration, dynamic distance and speed with or without the influence of gravity. - Accelerometer WikipediaAccelerometers in Electronics
MMA7260Q is a 3-axis accelerometer from Freescale Semiconductor. This accelerometer can be used with an extension Library Mma7260q which simplifies some initialization values and tilt detection.
ADXL105 Lower-Noise Wider-Bandwidth Accelerometer - The ADXL105, a near-ideal kind of vibration sensor, eliminates significant problems with existing vibration sensors, such as piezoelectric and bulk capacitive sensors. Primary benefits derive from much lower cost, stable sensitivity as a function of frequency and temperature, ruggedness, and ease of use. Besides machine health and condition monitoring, it is particularly well suited for noise and vibration cancellation applications.
A beginner's guide to accelerometers - By measuring the amount of static acceleration due to gravity, you can find out the angle the device is tilted at with respect to the earth. By sensing the amount of dynamic acceleration, you can analyze the way the device is moving.
Society of Robots' tilt to servo control app - How does it work? Inside an accelerator MEMS device are tiny micro-structures that bend due to momentum and gravity. When it experiences any form of acceleration, these tiny structures bend by an equivelent amount which can be electrically detected
