SparkFun 9DoF IMU Breakout – LSM9DS1 九軸運動感測模組

描述

SparkFun 9DoF IMU Breakout – LSM9DS1 九軸運動感測模組 3 軸加速度計、3 軸陀螺儀和 3 軸磁力計

SparkFun 9DoF IMU Breakout  是一種多功能的運動感應片內系統。它包含一個 3 軸加速度計、3 軸陀螺儀和 3 軸磁力計——在一塊板上有九個自由度 (9DOF)！STMicroelectronics 的 LSM9DS1 配備了數字接口，但即使這樣也很靈活：它同時支持 I ² C 和 SPI，因此您很難找到不兼容的微控制器。這個 IMU-in-a-chip 太酷了，我們把它放在您目前正在查看的四分之一大小的分線板上！

LSM9DS1 是少數幾款能夠在單個 IC 中測量運動的三個關鍵屬性（角速度、加速度和航向）的 IC 之一。通過測量這三個屬性，您可以獲得關於物體運動和方向的大量知識。LSM9DS1 從三個維度測量這些運動特性中的每一個。這意味著它產生九個數據：x/y/z 中的加速度、x/y/z 中的角旋轉和 x/y/z 中的磁力。LSM9DS1 Breakout 具有指示加速度計和陀螺儀軸方向的標籤，它們彼此共享右手規則關係。

LSM9DS1 中的每個傳感器都支持廣泛的範圍：加速度計的刻度可以設置為 ± 2、4、8 或 16 g，陀螺儀支持 ± 245、500 和 2000 °/s，磁力計具有完整的± 4、8、12 或 16 高斯的刻度範圍

SparkFun 9DoF IMU Breakout – LSM9DS1

The SparkFun LSM9DS1 Breakout is a versatile, motion-sensing system-in-a-chip. It houses a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer – nine degrees of freedom (9DOF) on a single board! The LSM9DS1 from STMicroelectronics is equipped with a digital interface, but even that is flexible: it supports both I²C and SPI, so 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 velocity, acceleration, and heading – in a single IC. By measuring these three properties, you 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/z, angular rotation in x/y/z, and magnetic force in x/y/z. The LSM9DS1 Breakout has labels indicating the accelerometer and gyroscope axis orientations, which 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 ± 2, 4, 8, or 16 g, the gyroscope supports ± 245, 500, and 2000 °/s, and the magnetometer has full-scale ranges of ± 4, 8, 12, or 16 gauss.
