  1. Wireless Sea Measurement UnitIntermediate Report A Plan for AarneHalme Project JuhaVanhalakka Erkka Mutanen

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

  3. Project Schedule Reprise • Project Plan 25.09. • Progress Report 30.10.+ electronics ready, code running • Demo A 20.11.+ casing ready, code ready • Demo B 27.11.+ mounting prototype done • Documentation done 10.12.

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

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

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