Arduino_LSM9DS1

Sensors

Allows you to read the accelerometer, magnetometer and gyroscope values from the LSM9DS1 IMU on your Arduino Nano 33 BLE Sense.

Compatibility

This library is compatible with all architectures so you should be able to use it on all the Arduino boards.

Releases

To use this library, open the Library Manager in the Arduino IDE and install it from there.

Usage

The ArduinoLSM9DS1 library allows you to use the inertial measurement unit (IMU) available on the Arduino® Nano 33 BLE board. The IMU is a LSM9DS1, it is a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer. The IMU is connected to the Nano 33 BLE board's microcontroller through I2C. The values returned are signed floats.

To use this library:

#include <Arduino_LSM9DS1.h>

The ArduinoLSM9DS1 library takes care of the sensor initialization and sets its values as follows:

  • Accelerometer range is set at ±4 g with a resolution of 0.122 mg.
  • Gyroscope range is set at ±2000 dps with a resolution of 70 mdps.
  • Magnetometer range is set at ±400 uT with a resolution of 0.014 uT.
  • Accelerometer and gyrospcope output data rate is fixed at 104 Hz.
  • Magnetometer output data rate is fixed at 20 Hz.
