Dear Sirs,
I read every topic in this thread (what helped me a lot), but now I'm stucked and need more help.
I did buy this sensor and I need to use it on my Orange Pi PC.
After following the instructions from this site together with the instruction of this thread, I wired the 3 cables like this:
RED -> 2 (5V)
BLACK -> 6 (GND)
YELLOW -> 35 (PA10)
My files are like this:
root@orangepipc:/sys/bus/w1# cat /etc/modules-load.d/modules.conf # /etc/modules: kernel modules to load at boot time. # # This file contains the names of kernel modules that should be loaded # at boot time, one per line. Lines beginning with "#" are ignored. w1-sunxi w1-gpio w1-therm #sunxi-cir ##xradio_wlan g_serial ##xradio_wlanroot@orangepipc:/sys/bus/w1# cat /boot/armbianEnv.txt verbosity=1 bootlogo=false console=both disp_mode=1920x1080p60 overlay_prefix=sun8i-h3 overlays=usbhost2 usbhost3 w1-gpio rootdev=UUID=88adacec-2194-4cfc-abc4-67cd6ef7fdf4 rootfstype=ext4 usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:uroot@orangepipc:/sys/bus/w1/devices/w1_bus_master1# cat /etc/default/cpufrequtils ENABLE=true MIN_SPEED=480000 MAX_SPEED=1200000 GOVERNOR=interactiveThe loaded modules are these:

Any help is appreciated.

Hello martinayotte!
Minutes after I posted my question, I found your first reply in another thread that lead me to the right path. I just don't replied here yesterday due to the limit of one post per day.
Beyond this, one of the pins was wrong. With Orange Pi PC and that sensor, the correct is use 3.3V, and not 5V. So, for the red wire, PIN 1, and not 2.
Now my temperature monitor system is alive and kicking!
Thank you very much!
