Under the winding blue waves of the Yangtze River, a group of special "fish" are quietly carrying out the important task of protecting the ecology - the intelligent bionic fish developed by Wuhan University, with its highly simulated appearance and advanced technology, has become the main force of ecological data collection in the Yangtze River. Behind its agile posture, the sensor group it is equipped with can be called the "smart eye", allowing the bionic fish to accurately perceive and scientifically analyze, and building a data defense line for the ecological protection of the Yangtze River.（Image sourced from the internet）

These sensors are like precise "environmental decoders", responsible for monitoring key parameters such as water quality, water temperature, and water flow velocity. When biomimetic fish shuttle through the complex water environment of the Yangtze River, water quality sensors can capture real-time indicators such as dissolved oxygen, acidity and alkalinity, heavy metal ions, etc., just like doctors diagnose the Yangtze River. Once a certain data deviates from the normal range, the sensor immediately feeds back abnormal information to the research team, providing key clues for water quality warning and pollution tracing. Water temperature sensors can sensitively sense subtle changes in water temperature, providing dynamic data support for studying the living environment and migration patterns of aquatic organisms in the Yangtze River.

In addition to monitoring environmental parameters, sensors are also the "navigators" and "safety guards" of bionic fish. In the turbulent and complex terrain of the riverbed, ultrasonic sensors and visual sensors work together to emit sound waves and capture images, constructing a three-dimensional map of the surrounding environment to help bionic fish avoid obstacles and accurately locate sampling points. At the same time, these sensors can also identify dangerous objects such as sunken ships and fishing nets at the bottom of the river, avoiding damage to bionic fish due to collisions and ensuring the safety of equipment and the continuity of data collection work.

In addition, sensors also bear the responsibility of recording biological information. Through sonar sensors, simulated fish can detect the species, quantity, and distribution of fish, and draw a "dynamic map" of the biodiversity of the Yangtze River. Researchers can analyze changes in fish population structure based on this, providing scientific basis for the protection of rare species and sustainable utilization of fishery resources.

With the deepening of the Yangtze River conservation strategy, the sensors carried by intelligent bionic fish are also constantly upgrading and iterating. In the future, more sensitive and miniaturized sensors will be integrated, enabling them to detect finer environmental changes and even track the migration paths of specific pollutants. In the battle of ecological protection in the Yangtze River without gunpowder, the sensors of intelligent bionic fish will continue to play a key role in safeguarding the health and sustainable development of the Yangtze River ecosystem.
