How to use Linux command or Python code get Raspberry PI's Temperature All In One

如何使用 Linux 命令或 Python 代码获取 Raspberry PI 的温度

raspberry pi check the temperature

import gpiozero as gz
# read the temperature into a variable:

cpu_temp = gz.CPUTemperature().temperature

# round the value to one decimal place
# cpu_temp = round(cpu_temp, 1) ❌ bug

print("temp =", cpu_temp)

temp=$(('cat /sys/class/thermal/thermal_zone0/temp'/1000))
echo $temp

vcgencmd

$ vcgencmd measure_temp
temp=47.2'C

$ vcgencmd measure_temp | egrep -o '[0-9]*\.[0-9]*'
47.2

$ watch -- 'vcgencmd measure_temp'
$ watch -c -b -d  -n 1 -- 'vcgencmd measure_temp'

$ vcgencmd measure_temp | grep  -o -E '[[:digit:]].*'
$ vcgencmd measure_temp | egrep  -o  '[[:digit:]].*'

cpu=$(</sys/class/thermal/thermal_zone0/temp)
echo "$((cpu/1000)) c"
