Attached the Required library's to the post i had trouble my self finding the right Dallas Temperature library since the person that made the guide seems to not list it on his site anymore,
i found this back after some searching on google
my temperature meter didnt work without that library.
My EC/ppm meter (sorry for the messy wiring)Β My wiring is for the updated script!(follow wiring of the guide you gonna use to make it)
what you see on the computer
Β
There is also a updated script wich includes code for a Lcd screen so you dont require a computer to see the measurements.
