Environmental Access Point (EAP) Full integration of environmental sensors The EAP is directly linked to the Akvasmart CCS Feed System via the AkvaControl software. Collecting and logging environmental data from one or multiple depths provides better control of the feeding and possibilities of analysis of environmental data compared to feeding data. The EAP (Environmental Access Point) is a robust sensor connection hub that allows connection of multiple sensors in one location. The two-way communication between EAP and the feed system is either wireless or hard wired. The EAP is then an active part of the feed system, allowing connection of sensors such as temperature, oxygen and current.
