Datasheet

Run the following code to import the necessary modules and initialize the I2C connection with the sensor:

If you're connected using SPI, run the following code to initialise the SPI connection with the sensor:

Now you're ready to read values from the sensor using any of these properties:

acceleromter - A 3-tuple of X, Y, Z axis accelerometer values in meters/second squared.

magnetometer - A 3-tuple of X, Y, Z axis magnetometer values in gauss.

gyroscope - A 3-tuple of X, Y, Z axis gyroscope values in degrees/second.

temperature - The sensor temperature in degrees Celsius.

In addition you can adjust some properties by getting and setting their values:

accel_range - The range of the accelerometer, should be a value of ACCELRANGE_2G, ACCELRANGE_4G,

ACCELRANGE_8G, or ACCELRANGE_16G from the adafruit_lsm9ds1 module. The default is 2G.

mag_gain - The gain of the magnetometer, should be a value of MAGGAIN_4GAUSS, MAGGAIN_8GAUSS,

MAGGAIN_12GAUSS, or MAGGAIN_16GAUSS from the adafruit_lsm9ds1 module. The default is 4 gauss.

gyro_scale - The scale of the gyroscope, should be a value of GYROSCALE_245DPS, GYROSCALE_500DPS, or

GYROSCALE_2000DPS from the adafruit_lsm9ds1 module. The default is 245 DPS.
