LSM9DS1 9-axis IMU 模組

通過LSM9DS1 9軸運動傳感器模塊，可以測量其方向，方向和運動。便利的SIP模組中提供了便利的原型設計，並且方便地研究運動跟踪中涉及的物理學。

WIth the LSM9DS1 9-axis motion sensor module, your inventions can measure their direction, orientation, and motion.  The LSM9DS1 is used on our ELEV-8 v3 Quadcopter's Flight Controller. We have made it available in a convenient SIP module for easy prototyping, as well as conveniently studying the physics involved in motion tracking.

This sensor is a “system-on-a-chip” that contains 4 different sensors: a 3-axis accelerometer (for measuring gravity or acceleration in 3D space), a 3-axis gyroscope (for measuring rotation), a 3-axis magnetometer (for measuring magnetic field strength - used to find Magnetic North), and a temperature sensor that can be used for calibration.

The LSM9DS1 9-axis motion sensor module can be used with nearly any microcontroller—it can be powered by 2.8, 3.3 or 5 volts and it uses either a 3-pin SPI interface or an I2C bus.  Use it as a single sensor—accelerometer, a gyroscope, a magnetometer, or a temperature sensor—or all of the measurements can be read together for use in inertial measurement or dead-reckoning applications.  It can also be configured to drive an interrupt when detecting impacts, free-fall, or magnetic field ranges.

特色<Features>

• Measures linear acceleration, angular velocity, and magnetic field strength on three axes
• Measures the temperature, and internally temperature compensates all readings
• Low power usage—great for battery-powered applications
• 16-bit precision with selectable sensitivity is adaptable to your project's needs
  
• Breadboard-friendly SIP form factor
  
  

應用<Application Ideas>

• Physics studies
• Stalled, tilt, and collision sensing
• Free-fall detection
• UAV control systems
