Researchers at Michigan State University Foundation's biotechnology research center rely on deionized (DI) water for their experiments.

But with a limited supply of DI water, they sometimes ran out before an experiment was completed.

Facilities Director Phil Hegge knew that the best solution was a costly upgrade to the center's ionization and filtration system. A low-cost temporary solution, however, was to give researchers up-to-the-minute data on the water supply. They could monitor the water level in the tank and know whether to reschedule an experiment.

See how Hegge was able to quickly create a simple interface that researchers now use to monitor tank levels from their own smartphones, tablets, or computers. Read the groov case study.
