Hi Everyone! Thanks for stopping by!
I'm relatively new to the electrical engineering and instruments and controls world, though I have 5 years experience as a mechanical engineer, so a little extra explanation is appreciated!
The question: I am trying to build a proof-of-concept circuit using an Arduino UNO that measures water level in an open container. What sensor would be best for this circuit? Ideally, the sensor should be able to be in direct contact with the working fluid (tap water) on one side - my intent is to measure the hydrostatic pressure of the water via a port and tube at the bottom of the container. The tube will be filled with water and attached directly to the sensor port. The operating pressure range is 0-1 psig. I am familiar with analog and I2C protocol but I can learn a different communication protocol if necessary.
I have spent hours filtering pressure sensors on Digi-Key and have tried a few options, most recently the NXP MPVZ4006GW7U. This sensor is nearly perfect, except the datasheet says "for dry gas" despite the datasheet also saying possible applications include water level detection, so I'm hesitant to hook up a hose full of water to it. I figure I'd reach out to the community to see if anyone else has experience with this topic.
Side note: if someone knows of a breakout board or similar assembly that already does this, please let me know. I don't need to reinvent the wheel.
If I can provide any additional information please let me know!
Thanks for your time! I appreciate any and all input!
