Design and Research of Underwater Communication Technology Based on LORA and PH Value and Salinity Sensor

In order to develop and manage the ocean space, a series of ocean development support technologies are needed. Through the design of the LORA module principle andimplementation of the LORA module and the port design and research of PH and salinity sensors, this paper helps to build through links between these equipment and devices such as deep sea exploration, deep diving, marine remote sensing, marine navigation, as well as with shore-based, space-based and air-based command agencies to achieve effective information transmission.
