Here we will learn the basics of RF module and how to use it as a standalone RF Transmitter and Receiver. Here we have explained the RF Transmitter and Receiver Circuit by controlling the LEDs ...

HT12E is an encoder IC that converts the 4-bit parallel data from the 4 data pins into serial data in order to transmit over RF link using transmitter. While HT12D is a decoder IC that converts the ...

The RF Receiver circuit can be powered from a standard 5VDC supply. Just as for the RF Transmiitter, the aerial (17 cm for 433.92 MHz) has to be mounted as close as possible to the RF IN (ANT) pin of ...

433MHz RF Transmitter and Receiver Module: Those are the transmitter and receiver modules we are using in the project. It is the cheapest module available for 433 MHz These modules accepts serial data ...

This project has two sections, one is transmitter section and the other is receiver section. At transmitter section, we use HT12E encoder and at receiver section, we use HT12D decoder. Here, we do not ...

Receiver circuit shown in Fig. 2 consists of 433MHz RF module (RX1), decoder HT12D (IC2), 5V voltage regulator 7805 (IC3), transistors BC548 (T1) and BD139 (T2 and T3), two solenoid locks connected ...

Transmitter receives serial data and transmits RF signal wirelessly to the receiver through antenna. LM7805 Voltage Regulator It converts 9V supply form battery into 5V, which is required by all the ...

IR transmitter unit emits 36kHz signal and is fitted on one side of the gate’s frame. IR receiver unit and RF transmitter module, along with the encoder, are fitted on the opposite side of the gate’s ...
