The Weather Station Receiver project has been crazy-popular, and now you can buy a pre-assembled 433MHz Receiver Shield from Freetronics so you don't even have to build the circuit yourself. Just plug it in, load the sketch into your Arduino, and away you go.
Even better, the Freetronics version of the shield uses an RXB6 module instead of the RXB1 that we used in the original project.
The RXB6 is a multi-mode module with better sensitivity than the RXB1, and by loading different firmware it can operate in different ways. The Freetronics shields are fitted with an RXB6 running on firmware that makes it behave in the same way as an RXB1 so it remains fully compatible with the original design while giving the advantage of greater sensitivity.
