IR receiver-transmitter interfacing with Arduino.RF Transmitter and Receiver Module Interfacing with Arduino.In addition to the above example circuit, You can also see this example on IR transmitter and receiver interfacing with Arduino. Here the IR transmitter circuit with encoder but the same circuit can be generated for RF just by replacing the IR transmitter. These addresses make them operate with their desired devices. Sometimes you may notice that different devices remote doesn’t operate with each other, it is because of there specific address. Each button of the remote sends the different data input on the encoder and then the encoder passes it to the output pin. You may notice that there are multiple buttons on the remote and each of them delivers a different function. To use the encoder with external devices always check for their voltages otherwise the encoder can be destroyed. Due to the availability of microcontrollers and other smart devices the input signal can be applied through their GPIO pins. The encoded signal gets the address and data in the form of logic states mostly. These pins are 4 in number and these four pins describe the data in the encoded signal. In those cases where two receiving end or sending ends have the same address, then devices start messing with each other. The address is like a security for the communication system. The broadcasted signal has an address that gets identified by the decoder to receive the data. Most of the devices attached to the encoder only broadcast the signal. The address pins are eight in numbers which describe the address of encoded signal. In these 12-bits, 8 of them will come from the address pins and the rest of them will be from data input pins.

The primary function of the encoder is to encode the 12-bit parallel input data and then forward it towards the output pin. The following diagram represents the internal structure of the HT12E. Smoke and builder alarm system encoder their message by HT12E.Most of the smart systems communicate with each other wirelessly which also has HT12E to avoid the load on the internet. Recently IoT production has been increased very much.In remote control systems, this encoder is widely available for encoding the data for transmission.HT12E Encoder datasheet HT12E Encoder Applications Only 256 different combinations of addresses are usable with HT12E.The encoder uses 0.1uA current with 5V at standby.The operating voltage range of the encoder is 2.4 to 12V.

The encoder can convert 4-bit data to serial data.It is available in two packages, SOP and DIP.RF and IR modules can use directly with encoders.In HT12E builtin oscillator only requires a 5% resistor to operate.

CMOS technology makes the encoder a low noise immunity device.

The encoder can encoder 4-word at a single time.

Voltages on this pin will make the IC functional. Pin 18 is a power input pin of the encoder. 12-bit data will come out from the DOUT pin and this pin will connect to the external transmission device. OSC1 pin will use with the external oscillator input or the second terminal of the 1M resistor. Pin 16 is an oscillator input pin of the encoder. An external oscillator is usable at the OSC2 pin. In HT12E there is an internal oscillator and it requires an external 1M resistor to operate which can be attached at OSC2 pin. Pin 15 is an oscillator output pin of the encoder. It only acts as a switch which allows controlling the transmission of data with the use of external devices. Transmission enable pin allows the data to transmit from data input to data output pins. Pin 14 is known as transmission enable pin. These pins are usable with any microcontroller or IC because only the logics state requires for data input on the data pins.ĬMOS Circuit with input Pull-UP high Resistors The encoder transmits 12-bit data which has 8-bit of address and 4-bits of data. Pin 10 to pin 13 are the data pin of the encoder. The ground pin needs to attach with an external device to make it operatable with encoder. Pin 9 is a common ground pin of the encoder. A specific address should be using secure communication. It is suitable in case of open communication. Most of the time, all these pins attached to the ground or power which makes all the address bits the same. Any of the combinations is useable as an address. The 8-bit address comes with a total of 256 different combinations. The logic state on these pins will set the 8-bit address.
