An attempt to create an USB/standalone weather station. LCD screen is to be added. Single sensor version depicted.

I use SHT10 for interior temperature and humidity (DS18B20 is ready to use for external temperature), MPX4115AP for air pressure, and FD-263-1 photo diode for luminance. I've ordered WH1602B-YYK-CTK LCD screen to use as "standalone" device and Arduino Proto-Shield to assemble the resulting schematics into a device.
