Procedures to setup the Rasberry Pi

Just to mention it, the current setup is not well documented, but let us start here. When switching on the Raspberry Pi we need to ssh to the address 130.149.148.195. Then we need to execute the following commands.

cd glucose_system
nohup python glucosesystem_server.py &
nohup python X_MeasureAllTheTime.py &
python glucosesystem_client_Setup.py

For the question about the port, you may choose "/dev/ttyACM0" If you try it in this order, it might work.

Glucose Measurement in Batch Cultivation

  • 4 reactors

  • 4 samples per hour

Glucose Timeseries

Callibration Standards

  • putting everything in a thermal block and measure on 37 degrees

  • initialization finished at 16:20

  • basline on 37 degrees 1010 mV

  • heat up the test solution 2 minutes on the thermal block

  • start with 2.5 g/L

  • afterwards we go down and measure 1.25, 1, 0.75, 0.5, 0.4, 0.3, 0.2, 0.1,

    0 g / L

  • then we did a second round of measurements to check if the sensors behavior

    is stable over time

Callibration Standards 9th of June

  • started initializing at 11 a.m.

  • put it in 2.5 g / L for one hour

  • at 12 p.m we changed it to 5 g / L

  • 37.2 degree celsius

  • Start all time data nohup python X_MeasureAllTheTime.py &

  • At 2:32 we are already down to 658 mV

  • put sensor in buffer at 2:33 p.m.

  • last standard is 1 g / L at 0:55
