The ARK Solar powered water quality monitoring buoy is a highly reliable and cost-effective water quality monitoring platform for data collection, communication, logging, alarming, control and analysis applications. It supports built-in water quality analyzers, depth transmitters, I/Os, cellular, Satellite module, RS485, barometer and GPS module. With robust IP68 water submersible enclosure, the product is ideally designed for surface water monitoring, such as reservoir, river, lake, ocean and water tank. Ultra low power consumption allows solar power to ensure 5 years of continuous operation. The RS485 port is able to connect, SMR digital analyzers, including depth, PH, ORP, temperature, conductivity, dissolved oxygen, turbidity, salinity, suspended solid, ammonium…etc. It is also able to connect third party devices such as flow meters and water quality instruments via I/O module and RS485 communication (Modbus RTU protocol).
