using HT12E for IR transmitter

[Bharath Kumar]

is it possible to make IR transmission from HT12E bcause some people said its meant only for RF not IR…..

 

 

if so kindly help me with some circuits

 

[Ashutosh Bhatt]

yes its is true. the HT12E protocol is design for RF channel. 

for IR there are different encoder decoder chips based on RC5 protocol

[Bharath Kumar]

can u name some IR IC which is abundant in market like HT12E for RF

[m venugopal]

Yes absolutely HT12E and 12D are for RF but by simple changes at transmitter we may use for IR also.

In order to use a IR LED you need to change the encoder to the HT12A series,

On the decoder side keep to use the HT12D.
