O Project Plan 25.09.O Progress Report 30.10.
+ electronics ready, code runningO Demo A 20.11.
+ casing ready, code readyO Demo B 27.11.
+ mounting prototype doneO Documentation done 10.12.
CodeO Xbee communication is workingO Measurement data logging incompleteO No tests done on the XBee chip O UI Code is lateO Challenges: learn PHP from the start,
learn JavaScript from the startO Also, possible changes in UI makes the
programming take more time and more difficult
HardwareO Hardware is on timeO We have a lab worker making us a
seabed mount steel tubeO Todo : power electronics
dimensioning, (battery capacity against solar panel power)
O Budget ?
Components PurchasedO We have ordered all parts from
Farnell and DigikeyO We have a WIKA hydrostatic
pressure sensorO We have a PT100 temperature
sensorO We have an industrial grade casing
