Answer by @Jack from the one of the comments: "@BadreddineZebbiche. I use this board to drive about 85 meters of telephone cable with multiple temperature sensors and only R pullup without any difficulty from a Raspberry Pi: abelectronics.co.uk/docs/stock/raspberrypi/1wirepi/…abelectronics.co.uk/docs/stock/raspberrypi/1wirepi/… I doubt your voltage drop will be of any real concern below 100 meters (telephone cable is about 6 Ohm/10k ft). I wrote an article on 1-Wire: packtpub.com/books/content/raspberry-pi-and-1-wirepacktpub.com/books/content/raspberry-pi-and-1-wire which might help. –"
