This output serial data is given to (SYN115) RF Transmitter. Address inputs A0 – A7 can be used to provide data security and can be connected to GND (Logic ZERO) or left open (Logic ONE). Status of these Address pins should match with status of address pins in the receiver for the transmission of the data. Data will be transmitted only when the Transmit Enable pin (TE) is LOW. 560k resistor will provide the necessary external resistance for the operation of the internal oscillator of HT12E. HT12D decoder will convert the received serial data to 4 bit parallel data D0 – D3. The status of these address pins A0-A7 should match with status of address pin in the HT12E at the transmitter for the transmission of data. The LED connected to the above circuit glows when valid data transmission occurs from transmitter to receiver. 12k resistor will provide the necessary resistance required for the internal oscillator of the HT12D. RF MODULES SYN115= transmitter 300mhz to 450mhz voltage=1,8v to 3,6v:max 5v SYN480R=reciever 300mhz to 440mhz voltage=3v to 5,5v
