Grove - 3-Axis Analog Accelerometer 40g (ADXL356C)

enter image description here

You can find a variety of 3-axis accelerometers on our website that can meet different scenarios and needs. This time, we bring you the industrial grade, high stability, high precision and low power ADI ADXL series three-axis accelerometers.

The Grove - 3-Axis Analog Accelerometer ±40g (ADXL356C) is a analog output MEMS Accelerometer. This sensor has two selectable measurement ranges: ±10g, ±40g. You just need to do little calibration work to get a relatively accurate result. The On-Board grove port can output two channel analog data: one for Z-axis, one for X/Y-axis. You can choose output the X-axis or Y-axis signal with the on-board switch. Also you can use the 4-pin welding hole to output X/Y/Z axis at the same time. The power consumption of this sensor is extremely low, 150 μA in normal operation mode and even only 21 μA in standby mode. You can switch the operating mode by changing the pad connection on the back.

The ADI ADXL Series Accelerometer includes four products that will meet your different range and output needs:

In addition, you can consider our new Seeeduino Lotus M0+, which is equivalent to the combination of Seeeduino V4.2 and Baseshield.


1 Please plug the USB cable gently, otherwise you may damage the port. Please use the USB cable with 4 wires inside, the 2 wires cable can't transfer data. If you are not sure about the wire you have, you can click here to buy 2 Each Grove module comes with a Grove cable when you buy. In case you lose the Grove cable, you can click here to buy.

Hardware Connection

  • Step 1. Connect the Grove - 3-Axis Analog Accelerometer ±20g (ADXL356B) to the A0 port of the Base Shield.

  • Step 2. Plug Grove - Base Shield into Seeeduino.

  • Step 3. Connect Seeeduino to PC via a USB cable.



If this is the first time you work with Arduino, we strongly recommend you to see Getting Started with Arduino before the start.

or you can just copy the following code.


This code is written for both ADXL_356B and ADXL_356C, and if you need to implement them on 356C, pls switch the line #define MODUEL_RANGE 20 with #define MODUEL_RANGE 40, or it will not work.

void loop()
  • Step 2. Upload the demo. If you do not know how to upload the code, please check How to upload code.

  • Step 3. Open the Serial Monitor of Arduino IDE by click Tool-> Serial Monitor. Or tap the Ctrl+Shift+M key at the same time. Set the baud rate to 115200.

  • Step 4. Calibration Follow the calibration tips in the Serial Monitor, just few step the calibration will be finished

  • Step 5. Now you can use this sensor, and the output will be like this:

Please Place the module horizontally!
Start calibration........
Calibration OK!!
Scale = 121
Raw data xy  = 185
Raw data z  = 193

x or y position acc is 0.00 g 
z position acc is 0.85 g 

Raw data xy  = 188
Raw data z  = 196

x or y position acc is 0.36 g 
z position acc is 1.21 g


If you use Grove port to output the data, the X axis and the Y axis can not be output at the same time, you can use the on-board swith to select the output channel. If you want to output X/Y/Z at the same time, you can use the 4 pin welding hole.


Q1: How to select the ±10g measurement range?

A1: To change the measurement range you need to modify both the hardware and software. First, cut the back pad which connected to ±40g and re-solder it to ±10g. Then modify the code in the code block line 12

#define MODUEL_RANGE           40
#define MODUEL_RANGE           10
