Jo Chou: SEA-LABS, CARNIVORES, Surf-IT Website

Jo Chou worked on SEA-LABS this Summer 2005 with Surf-IT. SEA-LABS is an underwater apparatus that will be able to provide real-time environmental monitoring of shallow-water habitats including coral reefs. The device, the POD (Programmable Oceanic Device), includes four sensors to monitor the ocean floor: pressure, temperature, salinity, and visible light. The POD is connected to a buoy floating above the ocean water, which holds an antennae that will wirelessly transmit the data to the main island (Midway).

Jo concentrated on working on receiving all the information, parsing the information to real sensor data, and making the data automatically upload to the local and remote database. This insured all the sensor readings were on the database as it was being read. All the data could then be easily viewed on the SEA-LABS webpage using simple PHP. For more information go to SEA-LABS.org.

Another project, CARNIVORES was also worked on. CARNIVORES is a small device which attaches to a dog collar and takes in accelerometer readings. The readings are taken along three axes and analysis is done using a square wave. The device is designed to display the movements of any carnivorous animal that has the collar around its neck.
