Soon 1-wire meteo station will start. They have temperature, humidity, barometer, wing gauge, and may be solar radiation.

All data will be posted on http://weather.zlatograd.com ( english ) and http://vremeto.zlatograd.com (bulgarian)

Now i explain why i have problem with my 1-wire barometer.

After few days i found one transformer from any pc device(i don’t from what, but over side write “ 14V 0.8A“ )  and i decide to make this transformer to supply my 1-wire barometer ..

And i put to this divice jack and power my 1-wire barometer and what happed !?

When I run OneWireViewer i found ALL is OK and program no say anythings Errors !!

All with 1-wire converter DS9097E !!!

Then I run Wserver and determinate – All Work very fine and program not say ANYTHING ERRORS !!!

Even Wserver read and DS18S20 !! I don’t believe because creator of this program sayd me .  

quote: I’m not sure about the DS2438 and external power – but I _KNOW_ it will not read a DS1820 temperature sensor if it’s connected through a DS9097E !

This is e-mail is send from ARNE !

That’s ALL

Now i coment that circuit and pcb what i make !!

First thing is that when power supply to 1-wire barometer is supply with 20V and more. The stabilizer begin heat up and the stabilizer MUST be put over aluminium or other cooler ! But effect of that heating is very BAD.

Thermo sensors display not really temperature and not showing accurate temperature !!

And issue is supply barometer with 12-14V and u don’t have a problems with accurate measuring of  temperature !

I will stop now and go to sleep :)
