What are you actually trying to achieve with it? The Pi OOTB has no onboard sensors of note, and the addons should likely be detected/accessed via GPIO or the IIO stack. > -- > [root@rpi3 ~]# sensors-detect > # sensors-detect revision 6284 (2015-05-31 14:00:33 +0200) > # DMI data unavailable, please consider installing dmidecode 2.7 > # or later for better results. > # Kernel: 4.14.0-0.rc6.git2.1.fc28.armv7hl armv7l > Use of uninitialized value in concatenation (.) or string at > /sbin/sensors-detect line 2867. > Use of uninitialized value in concatenation (.) or string at > /sbin/sensors-detect line 2867. > Use of uninitialized value in concatenation (.) or string at > /sbin/sensors-detect line 2867. > # Processor: ARMv7 Processor rev 4 (v7l) (//) > > This program will help you determine which kernel modules you need > to load to use lm_sensors most effectively.
