[net.analog] Digital Temp. Controller bd

chip (04/10/83)

     I am in need of a cheap/accurate digital temperature controller
   w/display (or, in the case of a chip, display driver). The
   controller's temperature should be settable (as you would set the
   date or alarm on a digital clock) and should show the sensor's
   temperature when not in any "set" mode. The output need only drive
   a led or optoisolator.
     Casio makes a watch with a temperature sensing circuit that beeps
   if the temperature falls outside some presetable boundaries. Surely
   if they could put this feature in a $50 digital watch, somebody would
   have built a digital temperature controller along similar lines.

   Anybody know of such a beast?

		     Any ideas/information would be appreciated,

Chip, just because something can be done, is needed, and would sell is no
reason to believe it will be made.  Good luck on your quest, but I wouldn't
give bets on you finding anything.  I am wearing a digital watch that cost $13
and tells the time and date, is a stopwatch and musical alarm.  A & P was
selling a plastic version for $1.50 (with a coupon), and there are pens
available with the time and date for about $3.  Yet, in all the many millions
of $$$$$$$'s worth of computers here, there isn't a single clock chip!  We are
constantly having to fight the file creation times that are off  --  sometimes
by whole days!  Bet the Japanese computers when they arrive will be able to
tell time (and maybe even the temperature).   Mel Haas  ,  houxm!mel
