Solar-powered outdoor weather station with PC logging and graphs
I have always enjoyed reading/doing projects that involve sensing various environmental parameters and recording them. This Solar-powered outdoor weather station built upon the Arduino platform measures the ambient temperature, humidity and barometric pressure, and send these parameters to a PC using XBee RF modules. The measurements are recorded on the PC and presented in nice charts showing their temporal trends.

The beauty of this project is that the outdoor module is fully powered through a Lipo battery which is charged through a solar panel. Sensors used in this project are DHT22 for temperature and relative humidity measurements, and BMP0805 for measuring barometric pressure.
