PIN DESCRIPTION

433mhz RF wireless transmitter and receiver kit

HT12E Encoder IC

HT12E is an encoder integrated circuit of 212 series of encoders. HT12E converts the parallel inputs into serial output.

HT12D IC

HT12D is a decoder integrated circuit that belongs to 212 series of decoders. HT12D converts the serial input into parallel outputs. It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins.

CIRCUIT DESCRIPTION

  3. RF Transmitter pin vss connected to the positive supply, GND pin connected to the GND and DATA pin connected to the Pin 17 of HT12E IC.
  4. Pin 15 of HT12E IC to connected 750K(470K+220K+68K{in series connection}) Resistor and Resistor 2nd leg connected to the Pin 16 of HT12E IC.
  5. HT12E IC Pin 8,9,10 & 11 connected to the each Push Button 1st led and each Push Button 2nd leg is GND.
  6. Breadboard connection positive to positive and negative to negative.

(B) Receiver connection:-

  1. HT12D IC and RF Receiver connected to the breadboard.
  2. HT12D IC Pin 1,2,3,4,5,6,7,8 & 9 are GND and Pin 18 connected to the positive supply.
  3. RF Receiver Pin vss connected to the positive supply and GND pin connected to the GND and DATA Pin connected to the Pin 14 of HT12D IC and antenna pin to connected wire antenna.
  4. HT12D IC Pin 17 to connected led positive leg and led negative leg is GND.
  5. Pin 15 of HT12D IC to connected 33K Resistor and Resistor 2nd leg connected to the Pin 16 of HT12D IC.
  6. Pin 10,11,12 & 13 of HT12D IC to connected LED positive leg and negative leg is GND.
  7. Breadboard connection positive to positive and negative to negative.


WORKING

Communication over Radio Frequency has many advantages as it doesn’t require a line of sight connection between the transmitter and receiver as in case of Infrared communication.

The range of RF communication is very high when compared to IR communication. In this project, a wireless transmitter and receiver system using RF modules (RF Transmitter and R
