Receiving sensor data

The next step was to figure out how to receive the sensor data being transmitted to the display base station. There’s plenty of articles on the web describing parts of the puzzle, but I didn’t find any one article that explained it all. For testing I used a Freetronics LeoStick and a 433MHz RF receiver module set up on a breadboard, so I could leave the original sketch still running on my desktop feeding data to the web. The LeoStick was particularly easy to use as I could just plug it into a USB port and test code from anywhere in the house without being tethered to power.
