air temp. and water level detection
i'm looking for some ideas to build a device that will measure the air
temp. and the water levels in a rain gauge. anyone have suggestions?

Weather stamp applications that are well researched.
There are a lot of ways to get temperature direct from a chip
and the Stamp manual pretty much covers the basics, but on the rain
gauge, you might find that a tipping or rocking rain gauge will be
the simplest as all you need to do is count for a total and measure
time to determine how fast it is raining.

a thermistor instead of a pot. The raingauge will be tricky because
not all rain has the same conductivity. Perhaps a method of
measuring weight instead ov volume. . .

This is really a simple balance beam with a little
catch pot at both ends, when one fills up. the
weight forces it to tilt, allowing the other to start
to catch water. The tilt can be monitored by your favorite
method, and you can be very creative. IR, Hall effect,
very brief tipping bucket rain gage

TEXAS size rain gauge, (humor)

And even one from our professor of Op-Amps
a good bit of data on tipping bucket can be found at

It's a big page, it's about half way down,
but you can click on the #9 of the table of contents
Just be careful about freezing and not getting any readings at all!
Happy tinkering!
