Thanks again. We’ll probably stick with the SP-110 since we have a few already in the lab. I found in a datalogger manual that they recommend using it as a single-ended analog sensor, where the positive wire is the signal and the negative wire is an additional ground. I saw in the ADS1x15 library that there is a folder for singleended. Would I just follow that example and keep the wiring the same? Or would I wire both “ground” wires to the ground pin (black wire on the starter kit)?
