infrared and irda - help

good day guys,

1. whats the difference between infrared and irda ?
2. is it ok to use irda transcievers instead of using regular ir transmitters and recievers ?
3. whats the difference between remote control applications and data communication applications in ir/irda ?

im really confused between the two.

1. whats the difference between infrared and irda ?

tocmo

Infrared is an energy similar to visible light, but with a longer wavelength. Infrared energy is invisible to the human eye, however, while visible light energy is emitted by objects only at a very high temperature, infrared energy is emitted by all objects at ordinary temperatures.
Where as IRDA is a suite of protocols for infrared (IR) exchange of data between two devices, up to 1 or 2 meters apart (20 to 30 cm for low-power devices)

2. is it ok to use irda transcievers instead of using regular ir transmitters and recievers ?

tocmo

Yes, but your software has to follow the IRDA protocol standards. check IRDA standards and specifications at http://www.irda.org/

3. whats the difference between remote control applications and data communication applications in ir/irda ?

tocmo

Remote control applications are not confined or made to strictly follow the protocol standards whereas IRDA is a standard protocol defined. and every device must follow those standards to communicate over IRDA.

hello ajay sir
i wanna knw how to contruct the ckt diagram of this IR transmitter and reciever???
wats the steps or methods.. if u can please help me out

do you want to use IR for data transmission?

Transistor in above circuit are 2N3904

hey TPS
you design these ccts by yourself or get from internet????
