Water Quality Buoy Battery Selection

Can a buoy be used for remote monitoring of water quality variables?

In this paper we present the design of an open-source and low-cost buoy prototype for remote monitoring of water quality variables in fish farming.

What are the water quality parameters measured by the proposed buoy system?

In this paper, the water quality parameters measured by the proposed buoy system are water temperature, water velocity and flow direction, DO, and salinity. We used the EPK-P1FDo-AL DO and EPK-I1SA-SL salinity sensors, which are the products of eKoPro and are capable of measuring water temperature.

What are the requirements for a water pond buoy system?

The system must shield the electronics from conditions such as rain and dust. In addition, the sensor probes must be immersed at a specific depth in the water pond while still allowing for adequate water flow. The buoy has to be stable with respect to wind and water movement.

How does the proposed buoy system work?

The proposed buoy system autonomously measures temperature, velocity, DO, and salinity as water quality parameters and then forwards the collected data to the shore server for storage using a wireless communication channel.

What is a battery-operated data buoy?

The developed prototype is a battery-operated data buoy for measuring temperature, dissolved oxygen and pH with the possibility to extend to other water quality variables, as shown in Fig 1.

Can buoys be installed in shallow seawater?

Our research also aimed to study the feasibility of installing these buoys in shallow seawater and monitoring their performance in marine environmental conditions. For the first time, such buoys have been deployed in the marine protected area of Capo Carbonara, Sardinia, Italy, for environmental monitoring.
