Here is my request: be really specific and fill in this table with your version of hypotheses and experimental tests. You kino of did that implicitly a bit above, but let's be really specific. Then you can do the tests and fill in the outcome column. Welcome to the scientific method! Sound OK?
| hypothesis | test | outcome |
|---|---|---|
| Sensors have some kind of problem | Change out a sensor with one of the spares | This seems to bring the voltage closer to the 3.3V max but is still slightly above, ~3.7V |
The sensors can run between 9 and 12V, with 12V being the "optimal," but maybe they just need to run at a lower voltage. | Change the voltage | This seems to get most of the sensors within the proper range, but I don't know if this is the ideal way to achieve that. |
Issues Encountered
- When all 8 sensors are plugged into the Lab Jack, the sensors output very small voltages. The voltmeter reads out a cycling voltage. It seems to be a problem with the power source.
- With the outlet by in the office it seems it can only deliver constant voltage to 1 sensor. More makes it cycle
- With an outlet by the lab bench, it can deliver constant voltage to 5 sensors. The 6th makes it cycle
