The APB5 is designed for monitoring water quality in coastal waters, fjords, lakes and fish farms. The buoy contains a control unit, CU801B, an Embedded Web Server, a GSM/GPRS/EDGE or satellite (IMARSAT/Iridium) router, a winch, a short range radio for communication with sensor unit, solar cells and battery pack. In fish farm application, the buoy is normally powered from an external supply. The control unit can be remotely programmed to desired profiling frequency and depth. In between profiles, the sensor unit rests above the water inside the buoy. This eliminates biofouling on the sensors. Since the sensor unit requires a wireless RS232 in/out feature, the CTD Muti-Parameter SD204 or SD208 is perfect for this use. The data is transmitted to the control unit, and the Embedded Web Server produces a web page accessible on the internet at the address: station.saivas.net ("station" to be given by the user). The user will provide a SIM-card, and when the buoy is powered up, the APB5 will configure itself. Besides programming and data collection, utility data are also available, e.g. diagnostic info for the buoy and sensor unit.

An expert system using data from APB5 for fish welfare in aquaculture has been developed by The Institute of Marine Research (IRM).
