Getting temperature from Raspberry Pi

I am currently developing some code for sensors to use with my Raspberry Pi, it came to my interest to get some temperature data from the Pi, a quick search give me a very good result.

Actually there are temperature sensors on the Pi

/opt/vc/bin/vcgencmd measure_temp

Added to cronjob
/opt/vc/bin/vcgencmd measure_temp >> ~/rpi_temp.log

This will append data to the log file.
