MPC-Buoy Installed in Poland - Milestone of the project ClearWater PMPC. Under the European Funded FP7 project, 2 MPC-Buoys have been deployed for research purpose in Lake Skrzyneckie Male in Poznan, Poland. Within the project, 2 Buoy types have been developed, a Master version and a Slave. The Master Buoy continually monitors the water quality, to determine algae blooms within the lake. After uploading this to a server, the most optimal ultrasonic program can be selected to target the present algae. The Slave Buoy communicates with the Master, to receive the ultrasonic program that should be operative.
