I need to transfer data over about 20m from a DS18B20(here is the )
to a Arduino board, I was wondering if I could use the much cheaper CCA cable?
Also can you please inform me in which cases must I go for the CU cable. The differences between the two types are obvious but I still do not know in which cases I should use CU type. I have found some information in which is stated that CU, due to it's lower resistance, is required in case the load is draining significant current. What about frequency?
