Barometers + Equipment parts

The medium price of barometer pressure in the level of sea is 1013,25hpa.Down of 1013,25hpa then we have low pressure and over 1013,25hpa we have high pressure.Now i tell you about the rules of pressure.When the barometer falls means deterioration,when the barometer rising means improvement.When the barometer fall slowly possible means change of weather.When fall quickly and stop the falling after some of the time,for example 2-3 hpa in 3 hours then we expect thunderstorms.When the barometer rising slowly then means good weather for big during.When the barometer rising rapidly then means good weather for small during.When it is steadly means good weather continuously.When the barometer rise or fall quickly comes strong wind.With rapid fall we expect strong south wind and with rapid rise we expect strong north wind.

La crosse ws 2300 weather station and the part of it,console,anemometer,rain gauge,remote sensor out Temp-Hygro.All the parts it have 10 meters cables, the anemometer and rain gauge conection to remote sensor out Thermo-Hygro and the weather data wireless goes to the console every 120 sec almost ,for quick weather data to console every 8 sec ,there is and wire conection bettwen remote sensor out temp-hygro and console like photo.


The new anemometer with cups model TX 20 La-crosse	I do experiment to put 40 meters total cable from out thermo -hygro sensor to console ,and 10+10 meters from anemometer to out thermo-hygro sensor ,and all work very fine	The colors of cables La-crosse 2300 from top is yellow,green,red,black ,can to add more cable with RJ 11 contacts is down of the picture this is extra,but here to Greece some telephones cable is not correct for use with it weather station ,we can to cut RJ 11 and to put the colors of cables at right places.You can view all the project Here.
