[0002] Water resource management faces severe challenges worldwide, and efficiently utilizing every drop of water is crucial in arid regions and agricultural irrigation. Traditional water wells lack automatic water level monitoring and alarms during operation, making it difficult to promptly and effectively address water overflows or leaks.

This not only increases installation costs, makes construction difficult, and makes maintenance inconvenient, but also reduces flexibility and makes them susceptible to environmental factors. When the water well is far from the factory building and there is no power nearby, it cannot respond to the operating status of the water well equipment in real time, shortening the equipment's service life.
