The MLX90393 is a tri-axial magnetic sensor capable of sensing very small fields (like the Earth’s magnetic field) while behaving as one would want and expect during saturation in larger fields (like a near by magnet). It turns out the favorite HMC5883L and other such sensors that are intended for compass applications have a low dynamic range but also strange and undefined behavior in large fields. Ted Yapo did an incredibly extensive characterization of the sensor over on Hackaday. He published his controlled experiments testing a few sensors and found the MLX90393 to be superior.

The MLX90393 can be used as a compass sensor but also works well as a non-contact controller (joystick), flow meter (with magnetic impeller), or a linear actuator positional sensor.

We do not plan to regularly produce SparkX products so get them while they’re hot!

Experimental Product: SparkX products are rapidly produced to bring you the most cutting edge technology as it becomes available. These products are tested but come with no guarantees. Live technical support is not available for SparkX products. Head on over to our forum for support or to ask a question.

This is an update to our original MLX90393 breakout board, now with Qwiic connectors! The Qwiic system enables fast and solderless connection between popular platforms and various sensors and actuators. You can read more about the Qwiic system here.

Features:

  • Dual Qwiic connectors for fast connection and optional daisy-chaining
  • Resolution: 0.161µT
  • Max full scale resolution: 44,000µT
  • Requires 3.3V
  • I2C or SPI interface (selectable jumper)
  • User selectable I2C address supports up to four sensors on the I2C bus at a time.

該MLX90393是同時表現為一個希望和在更大的字段飽和期間期望(如附近磁鐵)能夠感測非常小的領域(如地球磁場)的三軸磁傳感器。原來,最喜歡HMC5883L和意圖用於羅盤應用在大場低動態範圍也奇怪和不確定的行為等這樣的傳感器。泰德蘭耶普做了一個令人難以置信的大量的傳感器上的表徵Hackaday 。他發表了他的控制實驗測試了幾個傳感器,發現MLX90393是優越。

該MLX90393可以用作羅盤傳感器,但也適用以及非接觸控制器(操縱桿),流量計(具有磁性葉輪),或一個線性致動器的位置傳感器。

我們不打算經常產生SparkX產品因此得到他們,而他們是熱的!

實驗產品: SparkX產品正迅速產生,為您帶來最尖端的技術,因為它變得可用。這些產品進行測試,但配有沒有保證。現場技術支持不適用於SparkX產品。頭部到我們的論壇支持或問一個問題。

這是一個更新我們原來的MLX90393接口板 ,現在Qwiic連接器!所述Qwiic系統使流行的平台和各種傳感器和致動器之間的快速和無焊連接。你可以閱讀更多有關Qwiic系統在這裡
