Hi guys
I come across this little transmitter only tag, I am just curious how it may work. I am guessing the pic (12f629) send out some kind of on/off keying to the oscillator, and the receiver decode those info.
Another question is how can they make the antenna so short?? it's 433MHz transmitter!!
Thanks guys
