The RF transmitter transfers this serial data using radio signals. This serial data is sending to RF transmitter. The HT12E encoder transforms the four bit data from the four data pins that are attached to buttons into serial data.In order to appear the working of wireless communication between transmitter and receiver, four LEDs light at receiver side are controlled by four buttons at transmitter side. The transmitter and receiver segments are placed at a distance of 20 meters.

We can utilized the radio signals to transmit the data.

The main purpose of this project is to execute a wireless transmitter and also a receiver by using RF device.

Apparently, the other resistor is joining between the oscillator pins of decoder. The main purpose is to enable the oscillator. This is used to show a successful transmission of data.Ī resistor is attached between the oscillator terminals of encoder. An extra LED is attached to Valid Transmission pin of the decoder. The receiver division consists of RF Receiver, HT12D Decoder with four LED light. The transmitter division consists of an RF Transmitter, HT12E encoder and having four push buttons. The circuit is cut on parts one is transmitter and receiver sections. To accomplish the wireless transmitter and receiver, we have to use an encoder IC and a decoder IC. The wireless transmission is done using radio frequency signals that are adjusted by using Amplitude Shift Keying technique. The range of RF communication is very large when compared to IR communication.Īn RF Transmitter and Receiver pair is utilizing for wireless communication. RF Module circuit using HT12E HT12DĬommunication over Radio Frequency has many advantages as it does not need a line of sight join between the transmitter and receiver in case of Infrared communication.

I am going to talk about circuit diagram, and working of this project. Hi Friends! In this project(RF Module circuit ), a wireless receiver system using RF device RF Transmitter and RF Receiver) is executed.
