Hello, I'm trying to make a new sensor type to measure the water in a water tank for my clay 3D printer, any suggestions as to how I should go about making this? I tried to make a duplicate of the thermistor sensor and haven't had any luck.

I've built a capacitive water sensor before now. I used a coil of insulated wire running insure the tank and measured the capacitance between the coil and ground. Measuring capacitance using a microcontroller such as an Arduino is straightforward.

We need more information. What are you trying to measure? Water temperature, water quantity, water quality, water pressure, water pH...?

Assuming it's water temperature, given your thermistor attempt?
