Process Controller
- Gemma and Ian set up the process controller over the weekend but empty state was not working correcting and the value shut off after it opened.
- Monroe helped solve the problem by creating a new empty state
- Problem with previous old state unknown
Running Experiment
- Filled the bucket and set up the automated process controller to collect data
- Pressure data is being collected per second
Next Week
- Analyze collected data
- Make necessary changes to set up (position pressure value so it cannot be moved)
- Run a test with a know initial level of water in clay pot

New Setup
- Attached pressure sensor at the bottom of collection bucket
- Will manually empty bucket when it fills
- Determined that the clay pot will not affect the water level in the collection bucket
Process Controller
-Fixed pressure sensor issue (pressure not being recognized by process controller)
-Deleted "Empty" state
-No longer automated, locked in manual "data collection state"
Next Week
-Have several runs of data
-Analyze data
