Reading Sensors

The X3522 adapter has various sensors for temperature, voltage and currents. Their values are
output using standard Linux conventions:
• The sensors command provides a formatted view of the values
• Alternatively, you can access the raw values via the filesystem.
Using the Sensors Command
For a formatted view of the sensor values, use the sensors command from the lm_sensors
package in your Linux distribution.
