Jobs

Base Stations

• Buy Solar/wind generators
• sense Power boards using base system
• Decide ip scheme
• Set up keys
• Build Base Boards - sort out power/heat issues
• ADC code for BatV and currents
• eeprom code and ringbuffer

Probes

• Power supply checks.

Results: the power supply for sensor, radio and msp430 can be controlled on/off respectively, all off current is 3.8-4uA, with uart on it increases to 264-267uA, still need: tests on all PCBs

• Temperature sensor

Results: Read the temperature about 25 centigrade, and set the configuration of sensor NEEDS: to test adc to Celcius code

• Tilt sensor.

Results: Read out its address 0x3A, and change the sensor's control registors NEEDS: calibration method, cal code, each probe's cal values (probably use calfile for all like before)

• External EEPROM.

Results: Read/Write data ok NEEDS: debugging and testing over full 256kB range, ring buffer tests

• Radio test.

Results: Tested it with help of the radiometrix development tool, transmit/receive are both fine when the radio turns on the current increases to 149.6mA, transmit increase to 172mA, receive about 152mA NEED: to test on battery pack - several TX packets to see if decoupling is OK

• Network tests

NEEDS:

• • • 3 probe test
    • packet lost test - what happens when oen probe goes offline or a packet is lost?
    • setup IDs on all PCBs

• Strain sensor

Results: signal changes when strain sensor deformed NEEDS: test in a real case, then calibration - DONE! NEEDS strain2N() for linux code

• Conductivity sensor

Results: small signal gets amplified NEEDS ADC to ohms/mS code and probably calibration offset

• Pressure sensor

NEEDS: to be tested and calibrated, possibly in water filled hole in Iceland! ADC to Pa conversion code

• radio

NEEDS PCBs made, antennas made, matching circuits for trials in Iceland, ribbon on every probe

• Code

NEEDS: completing and testing Build a two hops network with three nodes based on Contiki system, shell for base station control etc etc etc

Probe STATEs (AUTO mode = sensing regularly / MANUAL COMS mode = coms and responds to commands)

Server

• Sort out env firewall hole
• Sort out taking SVN
• Sort out mobile wifi

Misc

• Build new camera assembly
• Print & lamiate labels for boxes
• Print Poster for Cafe and Holmur
