Raspberry Pi Reflector (RPR): A Low‐cost Water‐level Monitoring System based on GNSS Interferometric Reflectometry. Water Resources Research , 2022; DOI: 10.1029/2021WR031713 Cite This Page : ...

Resa Ehsani, a UC Merced mechanical engineering professor, is developing a portable water sensor that can be used on all crops for better irrigation scheduling without changing current systems.

The new detection tool uses advanced technology to detect arsenic ions in water quickly and at extremely low concentrations. The sensor can measure arsenic levels as low as 0.90 parts per billion ...

These low-cost water level sensors are made of a small solar panel, batteries and an alarm. When water levels start to rise, city officials will be alerted by the ping.
