Water Pressure and Touch—interaction project

Hi everyone,

I need to measure the pressure at the bottom of a bowl of water (ranging from no water to a water depth of maybe 15 cm max), so need a pressure sensor with high precision and the right range. Have checked out a bunch of different sensors, but Grove - High Precision Barometric Pressure Sensor (DPS310) seems to be the best one so far if I can waterproof it. Could that work or should I try another approach?

I would also like to measure when someone touches the water in the bowl, and I currently don’t know how to do this, or if it can be done. If anyone has any ideas, it would be much appreciated.

Please let me know if there is any other information I need to provide to get help.

The weight of water is another way to calculate the amount of water in the container. There are waterproof sensors that can measure the weight of water when laid at the bottom of the tank.
What is the Weight of Water? (hy-techroofdrains.com)

Weigh the tank including liquid.

Will look into this, thank you.

Thank you paulpaulson, yes thought of that but would rather use pressure as users won't be able to "miss-use" the prototype. But will still consider this, maybe it's easier after all.

I this case take a search engine of your choise and ask the WWW for information about "Sensor Detector TL-136".

Followed the instructions, now I have a warrant out for my arrest. JK, that is great, thank you!
