[lm-sensors] lm_sensors in an embedded environment

[Robert Teel]

I am curious if anyone has tried to use the lm_sensor software in an embedded
environment.  I would like to get uClinux up on an FPGA or small micro, and run
lm_sensors on top of that to monitor other rack mount processor boards.

In other words, I want to a small embedded linux disto to monitor and alert the
maintenance personnel when there are chassis over heat / over voltage
situation.  Has this
type of thing been done?  I'm not concerned with the temperature of
the small micro, only the temps of chassis.

Feel free to reply to robt(at)Colmek.com.


Thanks in advance!

Hello Robert

You would most likely have to write the drivers your self.

[lm-sensors] lm_sensors in an embedded environment

[Robert Teel]

Has lm_sensors been successfully run on uClinux? The reason I ask is because
it sounds like it would make a great embedded system monitor for machine
temps, and other useful system data.

I can always check the forum, but just thought I would ask you first.


Thanks,
Rob

Just a small shell script monitoring sysfs values would do that, 
Temperature values are degrees Celsius x 1000 --> simple integer
compare.  No need for lm_sensors at all :o)

I don't remember anyone mentioning it on this list, sorry.

Keep in mind, lm_sensors consists of kernel drivers + userspace libs/apps.
If your embedded system is very resource constrained, you could ignore the
userspace bits and access the kernel drivers directly through /proc files
(kernel 2.4.x) or /sys files (kernel 2.6.x).

Sorry, it just occured to me that when I said "embedded system monitor" I
meant an autonomus, stand alone device that sits in the background and
measues power supplies, ambient temps, or any other external system data. I
was sort of envisioning a black box that ran linux, and was dedicated to
collecting maitenence information.

Seems like lm_sensor would be a good start, or am I way off base?


Thanks again,
Rob

Why would he? What would the benefit be, please?

I did some research on this subject, and I think lm_sensors would fit my
purposes well. I haven't confirmed if it would work on an non-mmu distro
(uClinux) though.

My goal for this is, as I have said, get uClinux running on a PPC core
inside and FPGA, or use some other small micro to run the lm_sensor package
in order to sense ambient temperature, fan tachs, and voltage levels. I'm
not interested in the core's internal temps or anything like that.

So far I have decided lm_sensors would work great, and I read somewhere that
someone had it working on a blackfin. Not to sure though since the
information was limited.

Of course it ould be a good idea to check this list first: 
http://secure.netroedge.com/~lm78/supported.html
And verify that the chips on the embedded device is on that list.
Many embedded devices does not have anything intended for monitoring 
temperature.
