#
# all entries have to be of the form:
# SENSOR=<device-file>,<dbname>,<description>,<entry>,<scale-factor>,<add>,<unit>
#
# <device-file>  path to the file under /proc which holds the device-data
#
# <dbname>       an unique filename for the database
#
# <description>  a brief description for the webpage
#
# <entry>        2 for fan-speed and 3 for temperature and voltage
#                this represents the position of the value in the
#                proc-file
#
# <scale-factor> correction-factor to scale the data correctly
#                ( to understand this look at the lm_sensors howto )
#
# <add>          value to add to shift the data correctly
#                ( for e.g. +12V - see lm_sensors howto )
#
# <unit>         unit to be shown in diagrams and on webpage
#                ( for example °C, V, Volts, RPM etc... )
#
# Example:
#
# SENSOR=/proc/sys/dev/sensors/gl518sm-i2c-0-2d/temp,temp,CPU temp,3,1,0,°C
#
#
#
# FreeBSD Users:
# The only fields required are:
#   <dbname>            which is an item from the left column in 'mbmon -rc1'
#   <description>       as above
#   <unit>              as above
#
# Example:
# SENSOR=,TEMP0,Motherboard Temp,,,,C
