This munin-node plugin reads a temperature value from a serial port,
|
|
provided by a Arduino with temperature sensor.
|
|
For details see: http://amber.bonhoeffer.nl/temperatuur/
|
|
|
|
|
|
Linux: "/dev/usb/ttyUSB[n]" or "/dev/ttyUSB[n]"
|
|
first for for RedHat, second form for Debian.
|
|
e.g. "/dev/usb/ttyUSB0"
