L3GD20屬于傳感器變送器的運動傳感器-陀螺儀。由意法半導(dǎo)體集團制造生產(chǎn)的L3GD20運動傳感器 - 陀螺儀陀螺儀運動傳感器 IC 和模塊用于測量或保持一個或多個軸上的方向和角速度。軸可能包括 X（俯仰）、Y（翻滾）和 Z（偏航），旋轉(zhuǎn)范圍從 100 到 6000 度。陀螺儀可根據(jù)靈敏度、模擬或數(shù)字、電源電壓、外殼樣式和輸出類型（例如模擬、I2C 和 SPI）進行選擇。

描述 Description

The L3GD20 is a low-power three-axis angular rate sensor.

It includes a sensing element and an IC interface capable of providing the measured angular rate to the external world through a digital interface (I2C/SPI).

The sensing element is manufactured using a dedicated micro-machining process developed by STMicroelectronics to produce inertial sensors and actuators on silicon wafers.
