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"
