Hi,
I want to send tone(4 Khz) via home power line(220v 50 Hz),the project is two parts transmit witch simply generate tone pulses with 4 Khs then modulate this signal via home power line and receive part
witch demodulate and filter the signal ,the project must be very simple and no need for home automation chips(like TDS5051).
anyone made similar job?I will appreciate suggestion and advice.
thanks...
Why home power lines? There is no simple solution for RF carrier current systems. This makes everything infinitely more difficult and expensive. That appears to be massive overkill for a simple annunciator.
Why not a simple RF ISM band device? NRF24L01 can be done for a couple of dollars for either end of the system. Or the even cheaper 433mhz devices.
thanks for replay
actually NRF24L01 is short range and 433mhz devices is so noisy ,also in wireless communication there is
interference, I need only send tone to specific slave.
