We can use microcontroller pins to control those pins and set configurations. In the above image, left one is HT12D the decoder and right one is HT12E, the encoder one. 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.
