Heath 5001 Weather computer outdoor temperature probe assembly

[Rob Frans]

Hi... the following are the IC's for making your own temperature sensors for
the ID-4001... I believe they are the same for the 5001, but I'm not
positive...
They are easy to make, and work great!... not to mention inexpensive!
Good luck, Rob K8RAF

"Hi Rob,
 inside the metal can on the end of the sensor cable heath used a linear IC
know as a  LM3911 temp. controller, they used it in a T-05 package (like a
big can transistor) and that matches the pinout shown on the schematic,
problem is those IC's have been discontinued and are hard to find, but
LM3911's are still available in an 8 pin DIP  package which are available at
the following URL http://www.elexp.com/ics_10cn.htm .
You will also need some 2 conductor shielded cable, preferably the foil type
shield for maximum shielding and then something to protect the IC from the
elements, I  dipped mine in epoxy, and then used a rubber like mix that is
made for coating tool handles.
 If you decide to go this route let me know and I will send you the
pinout/hookup for the IC's since the 8 pin DIP has a different pinout......

Hi,
  ok 2 conductor shielded cable with a white, black and shield wire...white
goes to pin 1, shield wire goes to pin 2 & 3, black wire goes to pin 4, pin
5-6-7-8 are not used...
now if you look at your schematic they show a coil on the outside sensor,
this was for rf protection but if you keep the cable as short as possible
and keep it away from any transmitters you shouldn't have any problems, at
least I haven't.
 Once your cables are built and sealed then hook them up and calibrate as
per the book, don't try to calibrate with just one hooked up, you need both
hooked up to calibrate properly.
 And one last thing I believe that place has a 20$ minimum, if you have to
buy 5 IC's to meet the minimum and don't want all 5 then I will buy 1 or 2
from you if you want, I like to keep spares around....
