Looking for water sensors and gsm module

Hi, I’m looking for libraries with water quality and conducibilty sensors. Someone can link them if you got it? I also need a library with a gsm module.
Thank you very much

Your best bet is a google search of the form “fritzing part name-model-number-of-part” where part name-model-number-of-part is the exact device you want. There are a number of sensors from Atlas Scientific (conductity and others) in core parts and some updated versions that I made for someone a few weeks ago in the forums. There are several GPS modules around as well.
