Raspberry PI: senza calore per la CPU PI

Se volete spegnere un Raspberry ad una certa temperatura, allora siete nel posto giusto. Ho uno script che controlla la temperatura della CPU tramite Crontab:

#!/bin/sh
#  This script reads the Broadcom SoC temperature value and shuts down if it
#  exceeds a particular value.
#  80ºC is the maximum allowed for a Raspberry Pi.


# Get the reading from the sensor and strip the non-number parts
SENSOR="`/opt/vc/bin/vcgencmd measure_temp | cut -d "=" -f2 | cut -d "'" -f1`"

# -gt only deals with whole numbers, so round it.
TEMP="`/usr/bin/printf "%.0f\n" ${SENSOR}`"

# How hot will we allow the SoC to get?
MAX="78"

if [ "${TEMP}" -gt "${MAX}" ] ; then

 # This will be mailed to root if called from cron
 echo "${TEMP}ºC is too hot!"

 # Send a message to syslog
 /usr/bin/logger "Shutting down due to SoC temp ${TEMP}."

 # Halt the box
 /sbin/shutdown -h now
else
  echo "${TEMP}ºC ok!"
  exit 0
fi

Lo script ha bisogno dei seguenti diritti:

–

Terminal

$ chmod 775 /usr/local/bin/checkTemp.sh

Possibile voce di crontab:

*/5 * * * * /usr/bin/sudo -H /usr/local/bin/checkTemp.sh >> /dev/null 2>&1
