Overview

The ADXL335 , ADXL326 and ADXL377 are low-power, 3-axis MEMS accelerometer modules

with ratiometric analog voltage outputs. The Adafruit Breakout boards for these modules

feature on-board 3.3v voltage regulation which makes them simple to interface with 5v

microcontrollers such as the Arduino.

The ADXL335 can measure at least +/-

3G in the X, Y and Z axis. It is perfect for

high-resolution static acceleration

measurements such as tilt-sensing, as

well as for moderate dynamic

accelerations from motion, shock or

vibration.

The ADXL326 can measure at least +/-

16G(!) in the X, Y and Z axis. It is ideal for

measuring more dynamic accelerations

from high-performance land and air

vehicles as well as for shock and impact

measurements.

The ADXL377 can measure at least +/-

200G(!) in the X, Y and Z axis. This is the

sensor for measuring extreme dynamic

accelerations encountered in applications

such as rocketry experiments and high-

impact shock measurements.

How it Works:

MEMS - Micro Electro-Mechanical Systems

The sensor consists of a micro-machined structure on a silicon wafer. The structure is

suspended by polysilicon springs which allow it to deflect in the when subject to acceleration in

the X, Y and/or Z axis. Deflection causes a change in capacitance between fixed plates and

plates attached to the suspended structure. This change in capacitance on each axis is
