Hi,
I have found this one:

Later I will connect it to Arduino and make some tests
Thanks,

There have been some favourable discussions over in the PICAXE forums on the HC-12, not too difficult to drive I gather.

Although 1000M is hardly earth shattering long distance, hundreads of times that are possible with other types of license excempt ISM devices.

Let us know how you get on with testing this device. At least after watching the video, it is clear how to open the polythene bag it comes in.

Too bad the United States requires an Amateur Radio license to use the 433 MHz band.

I have been thinking about getting a couple of hc-12. The 1000m range quoted, is that using the wiggly wire antenna provided, or using an external directional antenna (appropriate for the band)? Obviously I understand that the 1000m is unobstructed line of sight! Although it should penetrate walls much better than 2.4GHz.

Forget the antennas for a moment, by far the biggest impact on range is the environment the devices are being used in, hill top to hill top or dense urban area ?
