RF Transmitter and Receiver WRL-10535 and WRL-10533

Seems to be here:

  // Convert integer data to Char array directly 
  itoa(Sensor1Data,  Sensor1CharMsg,  10);

then sends it out
vw_send((uint8_t *)  Sensor1CharMsg  , strlen(  Sensor1CharMsg  ));

itoa is one of those C things that you have to know about to be able to look it up:
