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!
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.

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!
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 。
