Hardware Monitor/Sensor Add-on Boards?
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?"
It seems to me that you're barking up the wrong tree by asking what ISA boards are available to do the task. I find it unlikely that someone who was running a p200 server at home really wants to shell out *any* serious $$ for something designed specifically for the task at hand (I should know, being in a similar situation).
I mean, face it - if you really needed to run a server that was doing something worth monitoring cpu temp., fan speeds et. al - why would you set it up on old, likely flaky hardware?
No, setting up a p200 server for fun basically a hack - so why not treat it as such? Go all the way and build something! Heat sensitive resistors are cheap - with one op-amp, a control voltage and a comparator, you have yourself a heat alarm! Put a couple together, buffer it and run it into your serial port! The possibilities are endless.
