Freshwater level sensing

The current implementation

The level display functionality in even the most modern RVs is, at the very least, subpar. The most common approach involves a five-level indication: empty, 25%, 50%, 75%, and full. However, for my RV, this level of accuracy was inadequate. Therefore, I decided to enhance it with a more sophisticated sensor. The one I'm currently using is a pre-fabricated pressure sensor, which I sourced from AliExpress.

The sensor:

Mounted in the fresh water tank:

Link to sensor, opens in same window.

This sensor is capable of detecting water pressure within the range of 0 to 1 meter in depth and outputs a 4-20 mA current signal, proportional to the water depth.

Future implementaition, maybe
