With the increasing social pollution, many water sources have also been affected to varying degrees, making it increasingly difficult for people to use water. Many countries and regions have experienced shortages of drinking water. China has a huge population base, and the daily water consumption is also high.

During the signal transmission, it is easy to cause the signal strength to attenuate sharply due to the harsh environment in the field, so that the existing signal reception It is difficult for the device to receive the corresponding signal normally, which makes it difficult for people to take timely measures to deal with the water quality of the water source when it is affected, which greatly increases the probability of the water quality of the water source being polluted and reduces the protection effect of people on the water quality of the water source.
