To automatically maintain fish tank in an optimal condition.

But could this not be done by a simple stand alone chip?

Read my reply #37. It contains further details. The thermometer is part of a bigger system which maintains the entire fish tank. It may have been a really big fish tank but I am not sure. The following is an excerpt:

“A North American casino recently installed a high-tech fish tank as a new attraction, with advanced sensors that automatically regulate temperature, salinity, and feeding schedules.”
