描述

SparkFun Triple Axis Digital Accelerometer Breakout – ADXL313 (Qwiic) 三軸加速度計

SparkFun Triple Axis Digital Accelerometer Breakout – ADXL313 是一款低功耗,高分辨率(最高13位)3軸加速度計,可進行高達±4g的測量。該突破測量傾斜感應應用中重力的靜態加速度,以及由於運動或衝擊而產生的動態加速度。數字輸出數據的格式為16位二進制補碼,可通過板載Qwiic連接器(I 2 C)或SPI訪問。

ADXL313 Breakouts 具有高分辨率和低噪聲特性,可將傾斜度變化的分辨率降低至0.1°,而內置FIFO則有助於使用過採樣技術將分辨率降低至0.025°。集成的32級FIFO也可用於存儲數據,以最大程度地減少主機處理器的干預,從而降低系統功耗。額外的低功耗模式可實現基於運動的智能電源管理,並以極低的功耗實現閾值檢測和主動加速度測量。

輕鬆實現ADXL313 Qwiic突破設置。只需通過Qwiic連接器為加速度計提供電源和通訊,即可將其提供給所選的Qwiic開發板,您將一路順風。ADI公司ADXL313的示例用例包括汽車警報器,坡道起步輔助(HSA)系統,電子駐車製動器和數據記錄器應用程序(黑匣子)。

資源與文件

SparkFun 3軸數字加速度計分支-ADXL313(Qwiic)佈置在標準的1“ x 1”(2.54 x 2.54 cm)Qwiic分支板上,並包括標準的四個0.13“安裝孔,這些孔與M3螺釘兼容。

ADXL313

The SparkFun ADXL313 Breakout is a low power, high resolution (up to 13-bits) 3-axis accelerometer for measurement up to ±4g. This breakout measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Digital output data is formatted as 16-bit two’s complement and is accessible through the on-board Qwiic connectors (I2C) or SPI.

The ADXL313 Breakouts high resolution and low noise enable resolution of inclination changes of as little as 0.1°, while a built-in FIFO facilitates using oversampling techniques to improve resolution to as little as 0.025° of inclination. The integrated 32-level FIFO can also be used to store data to minimize host processor intervention, resulting in reduced system power consumption. Additional low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.

Getting the ADXL313 Qwiic breakout set-up is easy. Simply supply the accelerometer with power and communication via the Qwiic connector to your chosen Qwiic development board and you will be good to go. Example use cases for the ADXL313 from Analog Devices include car alarm, hill start aid (HSA) systems, electronic parking brakes, and data recorders applications (black boxes).
