Hi everyone I'm using a DS18B20 with the one-wire library on an Arudino Uno to measure temperature. Works great. I used a pull-up resistor between data and +5v as advised, however, while I understand the need for a pull-up (or down) resistor when dealing with inputs that a chip is monitoring, I do…

Pull up resister with DS18B20: why?

Thank you, everyone!

I appreciate the parasitic power diagrams are available on the datasheet but it's easier to learn through these discussions.
