• <sensor>_label contains a description of the sensor
• <sensor>_input contains the current value of the sensor, in thousandths of the base unit
(°C, V or A)
• <sensor>_max contains the warning maximum threshold for the sensor, in thousandths of
the base unit (°C, V or A)
• <sensor>_min contains the warning minimum threshold for the sensor, in thousandths of
the base unit (°C, V or A)
• <sensor>_crit contains the critical maximum threshold of the sensor, in thousandths of
the base unit (°C, V or A)
• <sensor>_alarm contains 1 if an alarm condition exists for the sensor, else 0.
Read the <sensor>_label files to determine the files correspond to a given sensor. For
example:
$ cd /sys/class/hwmon/hwmon1/device
$ grep -HT . *_label
curr1_label:
curr2_label:
curr3_label:
curr4_label:
in0_label:
in10_label:
in11_label:
in1_label:
in2_label:
in3_label:
in4_label:
in5_label:
in6_label:
in7_label:
in8_label:
in9_label:
temp1_label:
temp2_label:
temp3_label:
temp4_label:
temp5_label:
Note: The sensor names in these files are the same names that are output by the sensors command. See
Getting Output for a Specific
Then read the appropriate set of files to get information for a particular sensor. For example, if
you wanted to get information about the ambient temperature sensor for the FPGA, the previous
output shows that this information is in the temp2_* files, and so:
$ cd /sys/class/hwmon/hwmon1/device
$ grep -HT . temp2_*
temp2_input:
temp2_label:
temp2_max:
temp2_min:
