MBARI swFOCE (Shallow Water Free Ocean Carbon Enrichment Experiment) Sensor Node Instrument Simulator

Byungjin Bae, California Polytechnic State University - San Luis Obispo


Our swFOCE (shallow water Free Ocean Carbon Enrichment) sensor node instrument simulator uses a microprocessor to simulate various ocean sensors. Our system consists of an SD card, microcontroller board, and 4 nodes that will connect to the swFOCE sensor node from MBARI (Monterey Bay Aquarium Research Institute). Currently, our project can support a single node and simulates a pH sensor. The system will be connected to a computer through a USB cable, and also will be connected to MBARI’s swFOCE sensor node through a serial connection. When a query is given from the sensor node, the microcontroller will parse the data given from sensor node and search through the pre-installed data in SD card and return the appropriate data back to the sensor node. A user can set up our simulator through a computer terminal window.
