See also PIC Based Speed Controller using PIC16C54 Also due to encoding and decoding the noise level is very low. D stands for decoder which will be used in Receiver side and E stands for Encoder which will be used in Transmitter side. Need of Encoder and Decoders:ĭue to this drawback we have used encoder and decoder ICs, HT12D and HT12E. We checked with 5 meters distance and it worked perfectly. For this specific project we did not used external antenna and used 5V at the transmitter side. The transmission range is dependable on the voltage supplied to the Transmitter and the length of the antennas in both side. Also, same as the transmitter, this module also has an Antenna port we can solder wire in coiled form for longer reception. This is a RF circuit and we need to tune the transmitter at the perfect transmitted frequency point. If we couldn’t receive the transmitted data, there are possibilities that the transmitting and receiving frequencies are not matched. But it is a good practice to use both for lowering the noise coupling.Īlso, one thing is not mentioned in the datasheet, the variable inductor or POT at the middle of the module is used for frequency calibration. Those middle two pins are internally connected. The four pins are from Left to right, VCC, DATA, DATA and GND. In the above image we can see the pin-out of the receiver module. The receiving frequency is 433.92 MHz with a -105DB sensitivity. We can also add the antenna and solder it on the point denoted in the above image.įor the Receiver specification, the Receiver has a rating of 5V dc and 4MA Quiescent current as input. From the left to right the pins are VCC, DATA and GND. In the upper image we can see the pin-out of the Transmitter module. We can transfer data at a speed of 4KB/S with 10mW power. It does transmit in AM (Audio Modulation) protocol at 433 MHz frequency. If we see the specifications of the modules, the transmitter is rated for 3.5-12V operation as input voltage and the transmit distance is 20-200 meters.

Also go through below two articles to learn how to interface LCD and Keypad with PIC Microcontroller:

Reception Frequency will be 433Mhz using cheap RF TX-RX module available in the market.īefore going into the schematics and codes, let’s understand the workings of RF module with Encoder-Decoder ICs.

We will use encoder and decoder IC to transmit 4 bit data.

On the receiver side, we will receive the data wirelessly and show which key is pressed on the LCD.

On the transmitter side, we will Interface keypad with PIC and transmit the data.

We will interface Keypad and LCD with PIC microcontroller.

We will use PIC16F877A for the Transmitter and PIC18F4520 for the Receiver section.

In this project we will do following things:. Hello everyone, Today in this project, we will interface RF Receiver and Transmitter module with PIC Microcontroller and communicate between two different pic microcontrollers wirelessly.
