2. Contents O Project Schedule Reprise O Code O Hardware O Components Purchased O Building Board i-iv O Ready Chip O Casing O Mechanics O After Installation

3. Project Schedule Reprise O Project Plan25.09. O Progress Report30.10. + electronics ready, code running O Demo A20.11. + casing ready, code ready O Demo B27.11. + mounting prototype done O Documentation done10.12.

4. Code O Xbee communication is working O Measurement data logging incomplete O No tests done on the XBee chip O UI Code is late O Challenges: learn PHP from the start, learn JavaScript from the start O Also, possible changes in UI makes the programming take more time and more difficult

5. Hardware O Hardware is on time O We have a lab worker making us a seabed mount steel tube O Todo : power electronics dimensioning, (battery capacity against solar panel power) O Budget ?

6. Components Purchased O We have ordered all parts from Farnell and Digikey O We have a WIKA hydrostatic pressure sensor O We have a PT100 temperature sensor O We have an industrial grade casing from Ensto O List of components in Excel sheet
