Hardware Monitor/Sensor Add-on Boards?

Posted by Cliff on from the picking-up-what-your-motherboard-lacks dept.

DeeKayWon asks: "I'm going to be setting up an old 200MHz Pentium as a server in my house, and I'd like to be able to monitor things like the voltages, fan speeds and the CPU and chassis temperatures remotely using something like ksysguard. The problem is, the motherboard I have doesn't have a hardware monitoring chip. I would think that someone would be selling something like an ISA board with a sensor chip on it, but my search has been fruitless so far. Does such a beast exist?"

    As found on google.

    It looks like a small isa board.

  2. i2c on parallel port by cnvogel · · Score: 3, Informative

    the chips that sense your cpu-temperature or voltage usually connect to the SMBus which essentially is a simple i2c-bus.

    If your computer uses SDRAMS it already has this interface but it can also be found on some video-in-cards (where it controls the tuner (the i2c-bus is often used inside TVs or VCRs for this)) or you can wire it to a spare parallel port.

    So if your computer does not have those monitoring chips... you could just add them later.

    See http://www.netroedge.com/~lm78/hardhack.html for some initial info.

    Your kernel configuration (make menuconfig) may give you some hints, too... (Character Devices -> I2C-Support)
