In the kit Wireless Data Transmission (Bit Transmission) we will design a system to transmit digital sequence of 4- bit to the remote location and represents the signal 4 bit at receiver end.
The kit Wireless Data Transmission (Bit Transmission) demonstrates the basic concept of wireless digital data transmission. There are two different sections one is the transmitter and other is receiver section. In transmitter section consists of the 4-bit dip switch (representing four bit data).The switches are used in active low mode. The data bits are parallel but for transmitting the data should be serial therefore HT12E encoder is used which has 4 data lines and 8 address lines. It encodes the parallel data into serial data which transmitted over 434 MHz RF-channel using RF transmitter. Next The RF receiver receives the digital data serially on same carrier frequency and the decoder HT12D decodes the serial data give the same data bit as on transmitter which is indicated in the form of LED indications as the digital data bits.
