from http://www.analog.com/UploadedFiles/Data_Sheets/ADXL103_203.pdf
Use accelerometers to determine:
-
X, Y and Z acceleration (need three accelerometers)
-
vibration level
-
integrate acceleration over time to get speed
-
integrate speed over time to get distance in X, Y and Z

Inclinometer applications |
-
Use inclinometers to determine aircraft attitude: typically two attitude sensors are required for normal (ie. not acrobatic) flight.

PNI MicroMag3 three axis magnetometer module |
The MicroMag3 is an integrated 3-axis magnetic field sensing module designed to aid in evaluation and prototyping of PNI Corporation's technology. The MicroMag3 combines PNI Corporation's patented Magneto-Inductive (MI) sensors and measurement circuit technology for unparalleled cost effectiveness and performance. The MI sensors change inductance by 100% over its field measurement range. This variable inductance property is used in a cost and space efficient ASIC (PNI 11096) which incorporates a patented temperature and noise stabilized oscillator/counter circuit with an SPI interface. The microprocessor compatible SPI interface allows easy access to the MicroMag's measurement parameters and resulting field measurement data.
Advantages include 3V operation, low power consumption, large signal noise immunity under all conditions, and a large dynamic range. Resolution and field measurement range are software configurable for a variety of applications. The measurement is very stable over temperature and inherently free from offset drift.
These advantages make PNI Corporation's MicroMag3 the choice for prototyping, education and low volume applications. A reference design is also available for use in high volume applications.
