这就是我在寻找什么类型的建议的原因。使用塑料罐底部的HMC5883L进行了一些测试，并在水面上使用浮动的小钕磁铁。我能够在从传感器到磁铁的大约40-50cm的范围内获得非常好的读数。唯一的问题就像你提到的那个领域是如此强大，当水平下降信号增加非常大，所以也许不同的传感器可以更好地工作。
非常感谢，就像我之前提到的那样，这只是探索这个时间点潜在的技术解决方案。所以也许这个想法不是一个可行的解决方案。

That is the reason I am looking for advice what type. Have run some tests using the HMC5883L on the bottom of the plastic canister , and with the floating small neodymium magnet on the surface of the water. I was able to get quite nice readings in the range to about 40-50cm from sensor to magnet. The only problem is like you mention the field is so strong that when the level is dropping signal increase very heavily so maybe different sensor could works better.
Thanks a lot, and like I am mention earlier it is just exploration at this point of time potential technical solution. So maybe this idea is not an viable solution.
