Hi all,
I am trying to learn some basic RF comm, but am trying to float above the heavy theory.
I really just need to send '1' or '0' across about a 300m range, a sort of 'hey your car is being broken into' when a sensor trips.
So i've found a bunch of cheap receivers and transmitters and transceivers online - and they all use FSK or ASK modulation. The FSK seems to have better range than the ASK one. But I don't want to use a microcontroller.
So my question is, how does one produce an FSK modulation (but like really basic 'sending' or 'not sending' data), without a microcontroller?
What kind of components or ICs can I use to send a very simple signal wirelessly? Is it possible for a beginner, or do I need to get an EE degree first?
Thanks in advance,
Daniel
