transmitting audio 433mhz
dear friends.
i m doing a project on transmitting a temperature data ( in the form of voltage)
through readily available tx and rx. modules of 433mhz. pair.
my question is -- is the encoder and decoder chips are must at both the ends of rx and tx ..?
without the encoder can't i transmit the temperature data voltage comming out of the op-amp pins to the reciver and reciver can fed that to a microconteroller .?
In short i am stuch at the data trsnsmission point. my tx and rx have "data" pins available.. does that mean a "serial data " ..? i mist need to feed the serial data to the tx .?
please advise.. friends.
if some one have ckt diagrams related to this and if some one done the work previously in this area.
-- thanks in advance.
