Make your own wireless weather station

 Sure - you can get wireless weather stations from the usual electronics retail stores, however there's nothing like doing it yourself. Impress friends, family and also create exactly what you want by constructing your own. And this is exactly what Instructables user "bram2202" has done. Based around two small Arduino-compatible boards he has an outdoor enclosure that has temperature, humidity and barometric pressure sensors which transmits the data via 433 MHz data link back to an indoor unit. 

Housed in a customised enclosure, the receiver is again a simple build, with another Arduino-compatible with a 433 MHz receiver, and a nice 20 x 4 character LCD to display the relevant data. Furthermore the use of a passive infra-red detector can detect the presence of the user, and only turn on the LCD when required. 

It's a neat project and shows that you can make your own professional-appearing devices without too much effort. Visit the project page for the construction dialogue, sketches and tips. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

When embedding an Arduino into various projects where size is an issue, consider using our Freetronics LeoStick. It's the Arduino Leonardo-compatible board that's much smaller than the original:

 Apart from being one of the smallest Arduino-compatibles on the market with USB, it also has an onboard RGB LED and piezo which can be used a knock sensor and various tune and sound effects. Plus you can add extra circuitry with the matching protostick! For more information and to order, click here.
