Model recommendation: TH-SFA06Manufacturer of meteorological and environmental monitoring instruments and equipment, Yunjing Tianhe supports customized services for merchants. Choose Shandong Yunjing Tianhe for equipment. Don't worry, use the floating water quality automatic monitoring station - public participation in water quality monitoring work to jointly promote the improvement of water environment qualityThe floating water quality automatic monitoring station is an automated water quality monitoring device that integrates multi parameter sensing, IoT transmission, and solar power supply technologies. It uses buoys as carriers to achieve in-situ real-time monitoring of large areas of water, providing scientific and accurate data support for water quality management. It has significant advantages such as real-time monitoring, wide coverage, and low operation and maintenance costs, and is widely used in fields such as lake management, drinking water source protection, and industrial pollution control. The real-time monitoring capability is equipped with a high-precision sensor array, which can synchronously monitor key parameters such as pH value, dissolved oxygen, turbidity, conductivity, ammonia nitrogen, chlorophyll, etc. Some equipment can even extend the monitoring of special indicators such as COD and heavy metals. The sensor adopts optical and electrochemical detection technology, with high measurement accuracy and strong resolution, and can capture subtle changes in water quality. For example, when a sudden pollution occurs in a lake, dissolved oxygen drops sharply and ammonia nitrogen surges, monitoring stations can quickly sense and transmit real-time data to cloud platforms to provide timely warnings for management personnel. Traditional fixed monitoring stations have limited coverage due to their location, making it difficult to fully reflect the spatial heterogeneity of water bodies. Floating monitoring stations use buoys as carriers and can freely float with the water flow, achieving dual functions of "fixed-point monitoring+mobile tracking". In lake management, if abnormal water quality is found in a certain area, the equipment position can be quickly adjusted to track the source and diffusion direction of pollution, breaking through the limitation of fixed monitoring stations that focus on monitoring rather than treating the surface.

1、 Product Introduction
1. The SFA water quality float monitoring station is an unmanned collection system that integrates data collection, storage, transmission, and management. It is a hydrological automatic monitoring and reporting system aimed at industrial and agricultural production, tourism, urban environmental monitoring, geological disasters, flood control, water supply scheduling, power station and reservoir water management, etc; The powerful upper computer software can remotely observe real-time water and rain information, with functions such as database, report, and download. Users can also use the comprehensive meteorological software to further process and analyze the recorded data.
The SFA06 buoy consists of six parts: water quality sensor (water temperature, conductivity, pH, dissolved oxygen, ammonia nitrogen, turbidity), data acquisition instrument, communication system, power supply system, overall bracket, and water quality monitoring platform. At the same time, it can expand multiple water quality factors such as COD, chlorophyll, suspended solids, etc. The data acquisition device has functions such as data acquisition, real-time clock, timed data storage, parameter setting, and standard 2G/4G (GPRS) communication.
