Add motion, direction and orientation sensing to your Arduino project
with this all-in-one 9-DOF sensor. Inside the chip are three sensors,
one is a classic 3-axis accelerometer, which can tell you which
direction is down towards the Earth (by measuring gravity) or how fast
the board is accelerating in 3D space. The other is a
3-axis magnetometer that can sense where the strongest magnetic force is
coming from, generally used to detect magnetic north. The third is a
3-axis gyroscope that can measure spin and twist. By combining this
data you can REALLY orient yourself.
When we saw the new LSM9DS0 from ST micro we thought - wow this could
really make for a great breakout, at a very nice price! Design your own
activity or motion tracker with all the data... We spun up a breakout
board and Flora breakout that has all the extra circuitry you'll want,
depending on whether you are using it with the Adafruit Flora or an Arduino (or other microcontroller)
The breakout board version of this sensor has both I2C and SPI interfaces. Attaching it to the
Arduino is simple, power Vin and GND with 3-5VDC, and wire up I2C data
on SCL and SDA, and you're ready to go! More advanced users can use SPI,
our library has support for both. The breakout comes fully assembled
and tested, with some extra header so you can use it on a breadboard.
Four mounting holes make for a secure connection, and we put the popular
power+data pins on one side, and the interrupt pins on the other side
for a nice & compact breakout.
The Flora version has just I2C interface for a super-small design. Attaching it to the FLORA is simple: line up the sensor so its adjacent
to the SDA/SCL pins and sew conductive thread from the 3V, SDA, SCL and
GND pins. They line up perfectly so you will not have any crossed lines.
You can only connect one of these sensors to your FLORA, but you can
connect other I2C sensors/outputs by using the set of SCL/SDA pins on
the opposite side.
