FLORA Accelerometer/Compass Sensor – LSM303 – v1.0


FLORA Accelerometer/Compass Sensor – LSM303 – v1.0


SKU: WEAR-039 - Mfg Part Number: 1247


Add motion and direction sensing to your next wearable 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.

Adafruit has based this wearable breakout board 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 and sew conductive thread from the 3V, SDA, SCL and GND pins. They line up perfectly so you will not have any crossed lines. The boards are designed to be chained, meaning multiple FLORA I2C breakouts can be connected with lines of conductive thread without having to cross over any lines! The sensor can also be used with conventional soldered wire connections and conventional microcontrollers if needed.
