# Grove 3 Axis Digital Accelerometer 400g

![](https://raw.githubusercontent.com/SeeedDocument/Grove-3-Axis_Digital_Accelerometer-400g/master/img/Grove_3Axis_Accelerometer400g.jpg)

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.

## Platforms Supported

## 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](http://www.seeedstudio.com/depot/grove-base-shield-p-754.html?cPath=132_134). ![](https://raw.githubusercontent.com/SeeedDocument/Grove-3-Axis_Digital_Accelerometer-400g/master/img/Grove-3-Axis_Digital_Accelerometer_connect_BaseBoard.jpg)
2. Download the [Digital Accelerometer(±400g) Library](https://github.com/Seeed-Studio/Grove_3Axis_Digital_Accelerometer_H3LIS331DL) and unpack it into arduino-1.0\libraries in your Arduino installation folder.
3. 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.
4. Upload the code and open the serial monitor.
5. Open the serial monitor to get the adjust value of reference as the steps described in serial output. ![](https://raw.githubusercontent.com/SeeedDocument/Grove-3-Axis_Digital_Accelerometer-400g/master/img/Adjust_value_of_Accelerometer.jpg)
6. 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. ![](https://raw.githubusercontent.com/SeeedDocument/Grove-3-Axis_Digital_Accelerometer-400g/master/img/Redefine_the_VAL_of_Accelerometer.jpg)
7. Upload the code and open the serial monitor and open the serial monitor to check the result. ![](https://raw.githubusercontent.com/SeeedDocument/Grove-3-Axis_Digital_Accelerometer-400g/master/img/Raw_data_of_H3LIS331DL.jpg)
