EVAL-ADXL343Z-DB

ADXL343 Datalogger/Development Board

Product Details

The ADXL343 Development Board is an easy-to-use tool designed to shorten application development time by providing a ready-to-use platform for data collection and firmware development.


The board is pre-configured as a datalogger that can be used to gather data for refining algorithms, tuning thresholds, and generally familiarizing oneself with accelerometer data. Powered by two AAA batteries, the board is completely untethered and integrates seamlessly into portable applications. Logged data is stored on a MicroSD memory card, providing essentially unlimited memory capacity and operating system versatility. Data is stored in a text (.txt) file, so no software installation is required to operate the board or read data. A 2GB MicroSD card and a USB MicroSD card reader are provided with the board.


Additionally, the board is fully programmable, providing a hardware platform on which firmware can be tested in parallel with development of application hardware. Communications and processing are performed by an ARM7-based ADuC7024 micro-controller, and firmware is written in C. A programming cable is provided with the board, and a development environment and header files are supplied on this page. Finally, the platform can be duplicated in the final application, having already been tested with the application firmware. Schematics and layout can be found under the Supporting Documentation tab and can be used freely in your application.


Note that this board is not configured to display real-time data. For real-time evaluation of the ADXL343, please refer to the Inertial Sensor Evaluation Board. For a simple ADXL343 Breakout Board, refer to the EVAL-ADXL343Z.

EVAL-MST-ISEB

Real Time Eval System for Digital Output Sensor

Product Details

The iMEMS® Real Time Eval System is an easy-to-use evaluation tool targeting bench or desktop characterization of Analog Devices, Inc., inertial sensor products. The system consists of the inertial sensor evaluation board (ISEB), or main board, and a satellite board for any Analog Devices inertial sensor product. The ISEB connects directly to a PC via an USB cable, with the USB connection providing both communications and power to the board. The ISEB is connected to the satellite board through a ribbon cable. This cable allows the satellite to be easily manipulated for testing or separately placed into an environmental chamber for temperature or humidity testing. Separating the boards mitigates corruption of data due to the temperature and humidity effects of other components.

The ISEB is an universal main board and is intended to be used with various satellites of Analog Devices inertial sensors, including analog and digital accelerometers, as well as gyroscopes. The different products are evaluated by means of separate GUIs that are customized for performance and characterization measurements relevant to the inertial sensor being evaluated.

The EVAL-ADxZ-M system contains the ISEB and the EVAL-ADxZ-S satellite. Also included is an USB A to Mini-B cable to connect the ISEB to a PC and an 18-inch, 20-pin ribbon cable to connect the ISEB to the satellite.

EVAL-ADXL343Z

ADXL343 Breakout Board

Product Details

The EVAL-ADXL343Z is a simple breakout board that enables easy connection of an ADXL343 into an existing system. The ADXL343 is a digital-output, 3-axis accelerometer whose low power consumption and built-in features make it ideal for use in a wide variety of applications. Due to its small size, the EVAL-ADXL343Z has minimal effect on performance of the system and of the accelerometer, and thus it is ideal for evaluation of the ADXL343 in an existing system. Note that the ADXL343 must be communicated with digitally via SPI or I2C. No processor is included with the EVAL-ADXL343Z; firmware must be supplied externally by the user. For evaluation boards that include a processor, please see the EVAL-ADXL343Z-M and the ADXL343Z-DB.

Product Details

The EV-STRUCTURAL-ARDZ is a vibration sensor that uses the ADXL343 digital output MEMS accelerometer chip and the ADIS16203 programmable 360° inclinometer. Aside from providing vibration data, this sensor node also features the MAX30210 digital temperature sensor which gives the option to shut down sensitive machines and equipment for smart motor sensing applications.

The on-board inclinometer can be used to detect if the horizontal position of the sensor changes, which points towards a collapse of the structure where the sensor was deployed.

APPLICATIONS

  • Structural health sensor
  • Tilt sensing, inclinometers
  • Platform control, stabilization, and leveling
  • Motion/position measurement
  • Monitor/alarm devices (security, medical, safety)
