Grove - 3-Axis Digital Accelerometer(±400g)

pir

The H3LIS331DL is a low power high performance 3-axis linear accelerometer belonging to the “nano” family, with digital I2C serial interface standard output. The device features ultra low power operational modes that allow advanced power saving and smart sleep to wake-up functions. The H3LIS331DL has dynamically user selectable full scales of ±100g/±200 g/±400 g and it is capable of measuring accelerations with output data rates from 0.5 Hz to 1 kHz.

caution
The platforms mentioned above as supported is/are an indication of the module's software or theoritical compatibility. We only provide software library or code examples for Arduino platform in most cases. It is not possible to provide software library / demo code for all possible MCU platforms. Hence, users have to write their own software library.

Usage​

Here below we show you how to read the raw data from this accelerometer.

  1. Plug it onto the I2C port of your Grove - Base Shield.

    pir

  1. Download the Digital Accelerometer(±400g) Library and unpack it into arduino-1.0\libraries in your Arduino installation folder.

  2. Open the demo code directly by the path:File -> Example ->Grove_3Axis_Digital_Accelerometer_H3LIS331DL->H3LIS331DL_AdjVal. It is a sketch to adjust the raw data of H3LIS331DL to make it more precise.

  3. Upload the code and open the serial monitor.

  4. Open the serial monitor to get the adjust value of reference as the steps described in serial output.

    pir

  1. Open the demo code directly by the path:File -> Example ->Grove_3Axis_Digital_Accelerometer_H3LIS331DL->H3LIS331DL_Demo. Then modify the VAL_X_AXIS/VAL_Y_AXIS/VAL_Z_AXIS according to what you get from H3LIS331DL_AdjVal Sketch.

    pir

  1. Upload the code and open the serial monitor and open the serial monitor to check the result.
