#173672 - I think you mean MHz ? Responding to: ???'s previous message |

What's the matter with those $5 transceivers at 434 Khz (sic) that one sees from time to time? I think you mean MHz ? Like these: http://www.rfsolutions.co.uk/acatalog/...pment.html http://www.radiometrix.com/our-products/433MHz http://www.lprs.co.uk/ One thing to note: make sure you get one that is fully documented and supported by the supplier; the really cheap ones direct from China, etc, assume that you already know what you're doing - they come with no support and no documentation (as various posters here have found to their cost) Why would someone want to use a fancy-protocol-based module, most of the features of which are wasted if one wants merely to send or receive a signal once or twice a minute from the remote end of the link? Indeed - although we don't if what the OP's doing does require any "advanced" features. And, at the present rate, it doesn't seem likely that he's going to bother to tell us. :-( Looks like another Pigeon Post. :-( |
