RE: Temperature Monitoring

["Campbell" <c.macd@xxxxxxxxxxxxxx>]

Nick,

There was, a long long time a go,  a discussion about using a specific
temperature component from National Semi conductors....which had the
correct
voltage settings for using directly connected to Comfort. Unfortunately Nat
Semi couldn't or wouldn't supply in the UK and they were not readily
available in US. I'm also interested in this, If anyone has this working on
Comfort please let us know.

Lots in the archive about this, but nothing that quite fits....

I have a Comfort which will accept a variable (0 to +5 volt) input as an
indication of (for example) temperature.

So, I need something that can sit outside and deliver to Comfort a voltage
somewhere between 0 and 5 depending on the temperature.
Ideally, I'm looking at something like 0v = -10 Centigrade and 5v = 30
Centigrade.  In other words, a sensible spread of voltage across the likely
spectrum of temperatures here in the UK.

I do software not hardware and I'm stuck!

Ideas welcome - I can buy or, within reason, build.  I can't design!

Thanks in advance,

Nick
