Weather sensors developed within BigGIS project
The aim is to create a cheap wireless temperature/humidity sensors that can send sensor readings to a cloud through a gateway connected to a home router.

- Arduino Nano v3 @5V (MCU with USB-mini connector)
- ENC28J60 (ethernet module, not the same as original Arduino ethernet shield W5100)
- NRF24L01 + PA + LNA (rf module with built-in antenna)
- 3.3uF to 10uF capacitor (see also NRF24L01-Howto)
