Decoding and duplicating wireless RF data with Arduino

After being unhappy with the performance of his wireless thermostat, Steven Hale was motivated to create his own control system would communicate wirelessly in the same manner as his original unit to the heating system in his home. After determining the wireless link between the two was a simple 433 MHz RF data link, Steven captured the output from the transmitter using a PC and identified the pulses sent.

Then it was a simple matter of using an inexpensive 433 MHz transmitter unit and an Arduino to recreate the signal and now the boiler can be controlled by the Arduino. This has given Steven the framework to make his own Arduino or PC-controlled heating system which can be much more relevant to the residents of his home.

Doing so seems difficult however thanks to Steven's article you can sniff out RF signals yourself, so visit his website to get started. And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well.

If you're looking to work with your own RF wireless hardware, but don't want to make your own receiver circuit - check out our range of  315/433 MHz receiver shields:

Apart from being idea for working with the various low-cost data links on the market, the shield can also be used to capture wireless weather station data, as described in the book "Practical Arduino". For more information and ideas, check out the product page
