For a project I am working on I needed a really quick way of reading the Raspberry Pi’s CPU temperature, most of the solutions I found ran the command line
vcgencmd measure_temp
… via Python’s subprocess function and parsed the result.
This just wasn’t quick enough for my project as I needed something which would gather lots of data, not just the cpu temperature every second, so I pulled together my own module and class which reads the data directly from /sys/class/thermal/thermal_zone0/temp.
