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…[Read more]

It’s a simple, 3-wire analog sensor and I think it’s standard in weather station equipment. Does anyone have experience doing this, or a sketch to share?
