RS brings you a Design resource called DesignSpark. When i had to source some hard to find parts as a replacement or design component for a custom product, RS catalog was the answer.

The catalog would give an idea also of what parts are popular and summary specs. This was decades ago, now everything is Online, Datasheets, Manuals, Design resources, Application Notes and most important the Creative IP of many a Genius, from the world over.

The Web or Internet is the spirit of a True and Healthy Globalization, which is for Knowledge Sharing and Free Communication for Positive Growth of Skills. Most important, it enables an Intrepreneur (Internet Entrepreneur) to explore and establish his Trade Online with modest investments.

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. - Accelerometer Wikipedia

Accelerometers in Electronics

Sci-Spot.com - Accelerometer - An accelerometer is a device which measures acceleration; how fast it's speeding up. In the past an accelerometer could be a complex, bulky piece of equipment, but in
today's world, accelerometers are available as single ic's and use complex microscale machining technology.

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.

Balancing robot needs gyroscope and accelerometer

Populated Gryo PCB

ADXRS150 and ADXRS300 piezo-gyroscope integrated circuit, The gyro is very small at about 5mm square (about 0.3 inches square). You can see the small combo gyro PCB mounted vertically in the center section on the balancing robot

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.

triple axis accelerometer

AccelR8 is a device for measuring acceleration - AccelR8 is a device for measuring acceleration. It can measure +/- 2 g. As it contains a microprocessor, it an also measure time.

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
