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. |
The connections have some kind of problem | Take a sensor that works and plug it into each socket | If the sensor was reading out a voltage, it would read the same voltage out of every input, e.g. if it read 2.45V in AI0, then it would read 2.45V from AI2 and AI4 and so on. |
The sensors need to be calibrated to output between 0-3.3V?? unsure |
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
