Low cost weather station with remote control

This work describes use a PC to control home weather station and visualization measuring data via applications written in programming language C# with communications via USB or RS232. Weather station is capable of measure temperature up to five temperature sensors DS18B20, wind speed via measuring turbine with optical encoder, the intensity of illumination via light sensitive element and finally is able to detect an approaching thunderstorm by measuring atmospheric charge. The station also disposing eight galvanic separation switch outputs, whose function in the supplied software set to customer requirements. Visualization is done in the charts for each measured quantity and also in arranged the panel, depicting the actual situation.
