Add motion, direction and orientation sensing to your wearable FLORA project with Flora 9-DOF Accelerometer/Gyroscope/Magnetometer. Inside 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 easily orient yourself.
LSM9DS0 from ST micro is a great sensor which can be used to make smart wearable electronics projects. You can easily design your own activity or motion tracker with all the data this sensor provides. The sensor has a digital (I2C) interface. Attaching it to the FLORA is simple: line up the sensor so it is 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.
To start usig the sensor in your projects, check out Adafruit’s Arduino library. The example and library code will work 'out of the box' with Arduino. Simply download the library, connect the Vin+GND and SCL/SDA pins and upload the test program to read out 9 degrees of motion.
