Jetson Nano Temperature measurement

Hi, We observed that there is temperature difference between software measurement and actual external measurement of Tegra x1 . Also noticed that the temp deference increasing proportionally from ambient temp to max temp. The observed gap is 25’C to 30’C. Please support to fix the gap.

Moving to Jetson Nano forum for resolution.

hello senthil1,

may I know what’s the software approach you’re used to measure the temp.
thanks

We have took the temp data from the below approach:

CPU_temp=(cat /sys/class/thermal/thermal_zone1/temp) GPU_temp=(cat /sys/class/thermal/thermal_zone2/temp)
cpu=((CPU_temp/1000)) gpu=((GPU_temp/1000))

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

hello senthil1,

are you seeing same temperature difference with tegrastats utility?
