Buoy water quality multi-parameters monitor is a advanced water quality monitoring. Using buoy observation technology, water quality can be online-monitored all day, continuously, and at fixed sites, and monitoring data can be transmitted to control stations in real time. As part of the complete environmental monitoring system, the water quality buoys and floating platforms are mainly composed of floating bodies, monitoring instruments, data transmission units, power supply units (battery packs and solar power supply systems), mooring devices, protection units (lights, alarms). Remote monitoring of water quality and other real-time monitoring, and automatic transmission of monitoring data to the monitoring center via GPRS network. The buoys are arranged at each monitoring point without manual operation, ensuring real-time transmission of monitoring data, accurate data and reliable system.
