Researchers at the University of Texas at Dallas have created a portable food safety device they hope will one day be used at ...

Check out the new water level sensor circuit. The simple water level indicator circuit presented here makes this system automatic, i.e. it switches on the pump when the water level in the overhead ...

This design idea explains how to develop a water sensor circuit that can monitor upper and lower water levels.

[Bob] was having trouble keeping up with his water troughs. He had to constantly check them to make sure they weren’t empty, and he always found that the water level was lower than he thought… ...

Commenters told him that the best fluid level sensor was a hacked blood pressure monitor. He didn’t know that, and we didn’t either, until we watched his video, below.

Water level sensors serve an important purpose in rivers, warning of floods and unsafe recreational conditions. A new one is claimed to be not only more robust and reliable than others, but also ...

The stations will help provide real-time water level data for tide predictions and flood alerts. Sensors will be placed on marsh shorelines where flooding is a chronic problem.

I was thinking there must be a simple sensor that could tell me when the water level has fallen a set amount and automatically run the "fill pool" zone on the Rachio.
