The LSM9DS1 is a versatilemotion-sensing system-in-a-chip. It houses a 3-axis accelerometer3-axis gyroscopeand 3-axis magnetometer – nine degrees of freedom (9DOF) in a single IC! The LSM9DS1 is equipped with a digital interfacebut even that is flexible: it supports both I2C and SPIso you’ll be hard-pressed to find a microcontroller it doesn’t work with. This IMU-in-a-chip is so cool we put it on the quarter-sized breakout board you are currently viewing!
The LSM9DS1 is one of only a handful of IC’s that can measure three key properties of movement – angular velocityaccelerationand heading – in a single IC. By measuring these three propertiesyou can gain a great deal of knowledge about an object’s movement and orientation. The LSM9DS1 measures each of these movement properties in three dimensions. That means it produces nine pieces of data: acceleration in x/y/zangular rotation in x/y/zand magnetic force in x/y/z. The LSM9DS1 Breakout has labels indicating the accelerometer and gyroscope axis orientationswhich share a right-hand rule relationship with each other.
Each sensor in the LSM9DS1 supports a wide spectrum of ranges: the accelerometer’s scale can be set to ± 248or 16 gthe gyroscope supports ± 245500and 2000 °/sand the magnetometer has full-scale ranges of ± 2412or 16 gauss.
