When you think of biological pools, you would never imagine that an IT specialist would have anything to do with them. But this is exactly the case since we designed a remote monitoring system for our biological pools. For some years now, we have been equipping biological pools with sensor buoys, capable of transmitting [...]

Recently, a scientific study revealed that “A quarter of threatened freshwater fauna”, that is, at least 4,294 species of 23,496 freshwater animals on the IUCN Red List, are at high risk of extinction. We are far from considering that biological pools are part of the solution to this problem, no way! But at least [...]
