KX132-1211

KX132-1211 is a tri-axis digital accelerometer. It features a user-configurable 3-stage advanced data path (ADP) consisting of a low-pass filter, low-pass/high-pass filter, and RMS calculation engine. It also features an advanced wake-up and back-to-sleep detection with a high-resolution threshold capability configurable down to 3.9mg, a 512-byte buffer that continues to record data even when being read, as well as embedded engines for orientation, Directional Tap™/DoubleTap™, and Free fall detection. The sensing element is fabricated using Kionix’s proprietary plasma micromachining process technology. Acceleration sensing is based on the principle of a differential capacitance arising from the acceleration-induced motion of the sensing element, which further utilizes common mode cancellation to decrease errors from process variation, temperature, and environmental stress.
