The purpose of this project was to create a system to allow the Slocum G3 Glider to detect wave conditions while on the ocean surface, and to make it available to the communications modules inside the glider so that it can be sent back to shore.The measurements our system was designed to measure include up to 13 different characteristics of waves including swell height, period, and direction. This was accomplished using a low power microcontroller, SD card, and accelerometer on a PCB mounted in the glider’s science bay. As the glider has one primary battery as the main energy source, our system must be able to calculate the desired data all while consuming a minimal amount of power to minimize possible impacts on the glider’s battery life. The implementation of this project uses an STM32 microcontroller connected to an accelerometer. The microcontroller gathers data from the accelerometer and stores it in an SD card, as well as performing the Fourier transform on the data to send it to the main computer onboard the glider. The glider provides the board with a 17V power supply. A buck regulator is used on our board to convert the 17V down to 3.3V. One of our most notable accomplishments in this project was successfully dividing the electrical design of our system among multiple people and then integrating everyone's separate work onto our system PCB. We experienced some challenges with the firmware aspect of the project, however we were able to deliver a working system that meets the requirements we set out to accomplish.
