The ADXL335 is a complete 3-axis acceleration measurement
system. The ADXL335 has a measurement range of ±3 g minimum.
It contains a polysilicon surface-micromachined sensor
and signal conditioning circuitry to implement an open-loop
acceleration measurement architecture. The output signals are
analog voltages that are proportional to acceleration. The
accelerometer can measure the static acceleration of gravity
in tilt-sensing applications as well as dynamic acceleration
resulting from motion, shock, or vibration.
