This design aims to solve the current problem that the ocean temperature salinity meter in marine research has high accuracy, but the cost is high, and it is not easy to combine with other modules. This design is small temperature salinity meter with STM32F103 as the MCU using the temperature-conductivity integrated sensor and depth sensor. The accuracy mainly depends on the sensor. Users can replace the sensor to convert accuracy and control cost. The single-cell lithium battery is used as the power supply. It can be charged via USB, and can run for more than two hours. Communicated with USB, the upper computer can take the data from the lower computer to draw a curve and display the data at a fixed point on the computer screen, which is convenient for the user to analyze the data. The data is stored as a text file, and the user can place the data in other software such as Matlab for data analysis. This design provides a multifunctional and miniaturized instrument for the demands of the booming development of seafloor in-situ observation systems to conveniently measure salinity,temperature and depth of seawater and sediment.
