Product specifications
RF module is a set of RF transmitters (Tx) and RF receiver (Rx) and operates at a frequency of 433 MHz. RF Tx and Rx are encoded and decoded by a pair of encoder and decoder IC often HT12E and HT12D and uses ASK modulation technique. The module receives data serially and transmits wirelessly through the antenna. RF Rx receives data when RX and TX operate at the same frequency.
