Hello,

I need to make a simple circuit by connecting two DS18B20 sensors to an arduino controller to measure the temperatures at the inlet and the outlet of a water pipe. Can anyone please help me with the circuit and the code required for such setup?

NB : the distance between both sensors will be about 1 meter, which is the length of the pipe

The distance between the sensors is immaterial as far as Arduino is concerned.

Thanks Nick,

I have the circuit ready but I get an error when I try to upload the code.
