Using a variety of easy to use components including our Freetronics EtherTen board, Christian Murphy has designed and installed a temperature, humidity and light-level monitor which posts the results to cosm (the online service formerly known as Pachube). Temperature and humidity is measured by a DHT-22 1-wire digital sensor, and the light levels are simply read by measuring a light-dependent resistor. Finally, by mounting the equipment in weatherproof housings under the eaves, the system will survive the elements - as shown below:

When putting together your next Internet-enabled Arduino project - save time, space and money with the Freetronics EtherTen. Apart from being fully Arduino Uno-compatible, it has onboard Ethernet, microSD socket, full USB interface (so you don't need a costly FTDI cable just to upload a sketch!) and supports optional Power-over-Ethernet.
