Barometric Pressure

[signal_line]

Somewhere I saw an high accuracy barometer break out board for an Arduino. Don’t know if it would be sensitive enough. Same for the sailplane by variometer—may need a large barrel to be able to see the air escaping. I’ll look for that barometer and post a link.

Grove barometer has altitude accuracy down to one cm! About $12, but you need an Arduino—counterfeit for about $5.

Correction altitude resolution 0.01 meter (one centimeter). I think they cost more $21

Either I misread it or a misprint bug now I see 0.1 meter and some others at +-0.25 meter. If the pressure is changing it should give a reading.

Of course easy enough to watch the weather website and see which way the pressure is trending.

Sometimes approaching weather makes it harder for my dowsing. It is more related to the intensity of an electrically charged atmosphere.

I have heard that if the barometric pressure is falling it can cause unreliable locations.
,,What say those here? Anyone heard that before?
Thanks, elh

I HAVE A FRIEND THAT HAS AN LRL MAN SET UP AND HE HAS TO SET MACHINE FOR BM AND MOISTURE. SHORTRIB

The book is titled “Psychical Physics” by Tromp.

Air conductivity increases and PG decreases with decreasing barometric pressure.

Interesting about setting for humidity—that affects the speed of sound.

Interesting, a lot to consider.
