Temperature:    For such a high temperature a thermocouple is
(probably) the most sensible choice. Depending on requirements a
'Pyrometer" may be justified - measures wavelength of radiated infra
red. Thermocouples are MUCH cheaper. Even the common "Type K"
thermocouples sold in most electronics stores will work to over 1300
Celsius. The "sensor" is Nickel-Chromium/Nickel-Aluminium wire and is
potentially very cheap. Designs for thermocouple amplifiers are
available from various semiconductor makers.

Pressure  /Direction / Altimeter:    Look at the archives of recent
PICLIST discussions. There have been various mentions of all these in
the past few months. Someone here will be able to tell you how to
access the archives.

>1.  What I need is Temprature sensors (up to 1000 deg Celcius)
>2.  Presure sensors.
>3.  Directional (like a compas)
>4.  Someting to act as a Altimeter.
