RF Transmitter Receiver with Encoder Decoder Board
The RF Transmitter Receiver with Encoder Decoder Board includes a transmitter,
receiver, and integrated encoder/decoder for secure data transmission. This
module is commonly used in remote control systems
Description:
The RF Transmitter and
Receiver module with an Encoder-Decoder board is a complete wireless
communication system designed for secure and reliable data transmission. It
operates on 433 MHz or 315 MHz frequency and includes an encoder IC (HT12E) in
the transmitter and a decoder IC (HT12D) in the receiver. The encoder converts
parallel data into serial format for transmission, while the decoder converts
received serial data back into parallel format. This setup ensures error-free
data communication and is widely used in remote control applications, security
systems, and home automation.
