Does the NanoPi NEO-Air have an embedded CPU temp sensor ?

[pbuyle]

Is there an embedded temperature sensors in the NanoPi NEO-Air's H# CPU/SoC ? If yes, how does one gets its value. I installed the `lm-sensors `and `lm-sensors-detect` packages in FriendlyWrt but the `sensors-detect` command did not found any sensor.

Yeah, I am using thermistors, It really works well on NanoPi NEO-Air, I got it from reecoupons, 6 months ago, and there are many others are available too, if you wanna buy or need more options check once on there.

When you log in it auto gets at least the CPU temperature. Here is how mine looks.

So can get something like "phpSysInfo" to see that CPU temperature too? How would you do that. It has a /usr/share/phpsysinfo/phpsysinfo.ini file that I am sure can set it up in there somehow?

You can see the CPU with this one command:

cpu_freq

It does show the temperature of the CPU too in that commend.

Code: Select all

root@NanoPi-NEO:~# cpu_freq
Aavailable frequency(KHz):
        480000 624000 816000 1008000
Current frequency(KHz):
        CPU0 online=1 temp=45790C governor=ondemand freq=480000KHz
        CPU1 online=1 temp=45790C governor=ondemand freq=480000KHz
        CPU2 online=1 temp=45790C governor=ondemand freq=480000KHz
        CPU3 online=1 temp=45790C governor=ondemand freq=480000KHz
Current voltage(uV, vdd-cpux):
        1100000uV
root@NanoPi-NEO:~#

So shows the temperature of all 4 CPU's 45.7 celsius on my NanoPi NEO.
