1Buoy water quality monitoring stationFeature Overview
1.Buoy water quality monitoring stationSFB adopts an enhanced integrated cone structure to increase equipment stability and durability, which is more in line with float engineering.
Real time measurement of hydrological, water quality, and meteorological parameters within lakes or watersheds. The system integrates data collection and transmission, and has over limit SMS alarm function and automatic light sensing function. It has the characteristics of multiple measurement parameters, high measurement accuracy, large storage capacity, convenient networking, and stable operation. The buoy adopts an unmanned intelligent control system to complete the data collection and transmission of multiple sensors; The solar power supply system consists of solar panels and large capacity batteries, which can ensure the electricity required for long-term operation in the field; The buoy marker is made of ultra-high molecular weight polyethylene material, which has good anti-corrosion ability, prevents biological attachment, does not fade, strong collision resistance, lightning resistance, non-magnetic and other characteristics, and is suitable for complex hydrological and hydrodynamic conditions such as reservoirs.
The SFB05 buoy consists of six parts: water quality sensor (water temperature, conductivity, pH, dissolved oxygen, ammonia nitrogen), 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 turbidity and COD. The data acquisition device has functions such as data acquisition, real-time clock, timed data storage, parameter setting, and standard 2G/4G (GPRS) communication.

2、 Product Features
1. Easy to deploy: Various types of probes are highly integrated and easy to install; Provide free cloud platform services and quickly launch the system;
2. Easy to maintain: After installation, the equipment can work on its own without the need for manual monitoring, and can also be ensured to operate normally through remote monitoring;
3. Easy to expand: The sensor probes all use a unified communication protocol, which can quickly interface with the original equipment and expand monitoring parameters quickly;
4. Low power consumption: The device can operate for a long time in a low-power state, increasing the convenience of device use;
5. Real time performance: The data monitored by the device is transmitted in real-time to the cloud platform, improving the timeliness of environmental data feedback.
