Wondering how you mounted/installed your temperature sensor?
I bought something like this
but the algorithm to generate a temp out of it is pretty complicated.
I think a DS18 sensor would be easier to read, but I'm not sure how to mount in in a pipe without it leaking?
I used the sensor you linked and was able to read the data without issue on Arduino using a thermistor library. My code is posted here: Pool-Controller/Pool-Controller.ino at master Â· Here-Be-Dragons/Pool-Controller Â· GitHub
