App note: Free-fall sensing for drop-force modeling using a Kionix MEMS tri-axis accelerometer

in app notes by DP | 0 comments

Here’s another app note (PDF) from Kionix on their tri-axis accelerometer applications. An earlier set-up was used in the application note’s experiment. This application note describes how to use a Kionix MEMS tri-axis accelerometer as a free-fall sensor for drop … Read more

App note: Interfacing the KXP94 or KXR94 tri-axis accelerometer with the Texas Instruments MSP430F149 microprocessor to measure tilt and other motions

in app notes by DP | 0 comments

Capture motions with Kionix’ Tri-Axis Accelerometers and a TI’s MSP430F149. App note here (PDF) Kionix linear accelerometers function on the principle of differential capacitance. Acceleration causes displacement of a silicon structure resulting in a change in capacitance. A signal-conditioning CMOS … Read more
