The Water Quality Sentinel, also known as a miniature land-based automatic water quality monitoring station, is a automatic water quality monitoring system that uses multi-parameter water quality monitoring instruments and spectral sensors as the core, utilizes green energy such as solar energy and wind energy for power supply, utilizes modern sensor technology, and integrates automatic control technology, specialized data analysis software, and communication networks. It is applicable to online automatic monitoring of surface water. The functions are as follows:

(1) Provide a complete set of solutions, with a small size (covering an area of approximately 0.5-2 square meters), easy to move, strong functionality, and low investment, saving costs such as land acquisition, station building, and personnel.

(2) The monitoring points can be changed according to monitoring needs, suitable for long-term continuous online monitoring of different water bodies and temporary emergency monitoring of water bodies with abnormal water quality.

(3) Long term stability, low maintenance, and low overall cost of ownership.

(4) Continuously, timely, and accurately monitor the water quality changes of the main rivers and outlets in the city, and alarm when the monitoring parameters exceed the standard or the system status signal is displayed.

(5) By transmitting data remotely through communication methods such as GPRS, real monitoring data can be obtained anytime and anywhere.

(6) Automatic operation, power outage protection, and automatic recovery of incoming calls.

(7) Utilize green power supply systems such as solar energy and wind power.
