RF Transmitter and Receiver Circuit Diagram
Different RF transmitters are operated at different frequencies, according to the wavelength of the frequency the RF transmitter and receiver circuit is set up. Receiver Circuit The main function of transmitter and receiver projects receiver circuit is to receive the modulated signals transmitted via RF transmitter.
When this module receives the signals then it further demodulates it for RF communication to occur between two ends. There are various types of RF Receiver circuit; you can use the one which fits in your budget and process the most for transmitter and receiver projects and productive results.
This basically works as a wireless on or off switch.

transmitter and receiver projects And, the main purpose of this complete circuit is to send pulses from its antenna to a RF receiver. It is recommended to always use a continuous wave RF transmitter, so that you do not need to modulate the radio frequency waves.
Nowadays, this circuit has wide number of applications as it has made the wireless transmission a lot easier than before. The most transmitter and receiver projects example of a device which works on RF transmitter and receiver circuit is our remote controls. Almost, each one of uses remote everyday but do we ever wonder how it works from such a long distance.
The simple mechanism with the help of which you can easily access your television through a remote is through a RF transmitter and receiver circuit.
The extracted data in serial form is output at pin 2 of the module. It converts the serial data back to the parallel data after separating data and addresses.

HT12D belongs to the series of decoders and can be paired with series of encoders having the same number of addresses and transmitter and receiver projects format. HT12D is capable of decoding 12 bits, out of them 8 are address bits and 4 are data bits.
The 4-bit data is of latch type and when passed to the output data pins it remains unchanged until the new data is received.
The pin diagram and configuration of HT12D is as follows -: The data to be transferred is hard-wired with the help of switches at pins 10 to 13 of the HT12E Transmitter and receiver projects designated as D0 to D3 respectively according to the pin configuration of the IC.
Here 10K ohm resistors are used transmitter and receiver projects data pins as pull-up resistors. The address of the transmitter is also hard-wired. Here all address pins are grounded to allot transmitter an address of 0x A switch can also be connected to pin 14 of the IC to reset transmission.
The serialized data is passed on from pin 17 of the encoder IC to the pin 2 of the RF transmitter. A modulated carrier wave is output from pin 4 of the RF transmitter and transmitted through the antenna.
