RF module is a set of RF transmitters (Tx) and RF receivers (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 the ASK modulation technique. The module receives data serially and transmits it wirelessly through the antenna. RF Rx receives data when RX and TX operate at the same frequency.

  • Operating frequency: 433MHz
  • Open space operating range: 400 m with 45 cm antenna
  • Rx current supply: 3.5 mA
  • Rx operating voltage: 5V
  • Rx typical sensitivity: 105Dbm
  • Tx operating voltage: 3-6V
  • Tx output power: 4-12Dbm
  • Power consumption: low
  • Car alarm system
  • Wireless security system
  • Remote control car and robot
  • Automation

    Working as expected with good range covered.
    Don’t buy any other 433MHz RF module from anywhere Roboelements is selling good and right product.
    I’m really appreciate.
