Underwater Caves and the Dynamic Ocean
Underwater caves are one of the last frontiers unexplored on the planet. Our end goal is to gather information about the environments of these caves, such as water temperature and pH. The information gained about the environment of underwater caves could unveil new and pertinent trends in climate, sea-life, and energy, as well as possible developments in the fields of marine biology, meteorology, oceanography, and the Armed Forces. To accomplish this, we designed, developed, and tested a prototype for the Sensor and IMU subsystems of an underwater cave exploring device, stored this data in a remote database, and displayed this data on a GUI. Some of the materials used include a Raspberry Pi 3B+, an Adafruit 9-DOF Absolute Inertial Measurement Unit (IMU), an EZO RTD Temperature Circuit and EZO pH Circuit, and finally an Amazon Web Services (AWS) Relational Database. The system underwent three different stages of testing: IMU drift, battery performance, sending reliability, and temperature reliability. The prototype successfully completed all three of the performed tests and met expectations for our minimum viable product.
