SparkFun MLX90393 Triple Axis Magnetometer Breakout 三軸磁力計擴展板 (支援 Qwiic 系統)

現在是時候開始使用高級磁力計了,還有什麼比將它扔到易於使用的分線板更好的方法?  SparkFun MLX90393 Triple Axis Magnetometer Breakout 是一種三軸磁傳感器板,能夠感應非常小的磁場,同時仍然可以在較大磁場(如附近的磁鐵)飽和時表現出來。MLX90393 擴展板 可用作羅盤傳感器,但也可用作非接觸式控制器,帶磁性葉輪的流量計或線性執行器位置傳感器。為了更容易獲得您的讀數,所有通信都是通過I 2C 專門製定的,利用我們便捷的Qwiic系統。但是,如果您更喜歡使用麵包板,我們仍然會打破0.1“空間引腳。

SparkFun MLX90393 Triple Axis Magnetometer Breakout 三軸磁力計擴展板 MLX90393 是能夠感測非常小的字段,而表現為一個希望和在更大的字段(如附近的磁鐵)飽和期間期望的三軸磁傳感器。事實證明,最受歡迎的HMC5883L和其他用於羅盤應用的此類傳感器具有低動態範圍,但在大型領域也具有奇怪和未定義的行為。在Hackaday上,Ted Yapo對傳感器做了非常廣泛的描述。他發表了測試幾個傳感器的對照實驗,發現MLX90393更勝一籌。

MLX90393可用作羅盤傳感器,但也可用作非接觸式控制器(操縱桿),流量計(帶磁性葉輪)或線性執行器位置傳感器。分線板也是SparkFun Qwiic系統的一部分,因此您無需進行任何焊接即可找出磁場的外觀。

MLX90393的分辨率為0.161μT,工作電壓範圍為2.2V至3.6V,100μA。這個突破還配備了電路板背面的幾個跳線墊,一組允許你改變 I 2 C 地址以及一個可以將突破轉換為SPI模式(如果I2C 的方式不適合你)

It’s time to start utilizing the superior magnetometer, and what better way than to throw it onto an easy-to-use breakout board? The SparkFun MLX90393 Magnetometer Breakout is a triple-axis magnetic sensor board capable of sensing very small fields, while still behaving as one would expect during saturation in larger fields (like a nearby magnet). The MLX90393 breakout can be used as a compass sensor but also works well as a non-contact controller, a flow meter with a magnetic impeller, or a linear actuator position sensor. To make it even easier to to get your readings, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system. However, we still have broken out 0.1″-spaced pins in case you prefer to use a breadboard.

The MLX90393 features a resolution rate of 0.161µT with an operating voltage range of 2.2V to 3.6V at 100µA. This breakout is also equipped with a couple of jumper pads on the back of the board, a set that allows you to change the I2C address as well as one that can put the breakout into SPI mode (if I2C isn’t your cup of tea).

Features

  • Operating Voltage: 2.2V-3.6V
  • Current Consumption: 100µA (Typ.)
  • Operating Temperature: -20°C – 85°C
  • Resolution: 0.161µT
  • Max Full Scale Resolution: 44,000µT
  • I2C Address: 0xC0
  • 2x Qwiic Connection Ports
