• Classic 3-axis accelerometer can tell which direction is down by measuring gravity or how fast the board is accelerating in 3D space• Magnetometer can sense where the strongest magnetic force is coming from (generally magnetic north)•I2C interface• Attaching it to the FLORA is simple: line up the sensor so its adjacent to the SDA/SCL pins & sew conductive thread from the 3V, SDA, SCL & GND pins. They line up perfectly so you will not have any crossed lines. Add motion & direction sensing to your wearable FLORA project with this high precision 3-axis Accelerometer+ Compass sensor. Inside are two 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 magnetometer that can sense where the strongest magnetic force is coming from, generally used to detect magnetic north. By combining this data you can then orient yourself. We based this sensor on the latest version of this popular sensor, the LSM303DLHC. The sensor has a digital (I2C) interface. Attaching it to the FLORA is simple: line up the sensor so its adjacent to the SDA/SCL pins & sew conductive thread from the 3V, SDA, SCL & 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. Get started with the FLORA Accelerometer click here for the guide! It uses the same Arduino library as our conventional form LSM303 breakout. The example & library code will work 'out of the box' with FLORA. Simply download our library & connect the 3V/SCL/SDA/GND pins, install the library properly & upload our test program to read out accelerometer & magnetic field data.
