nikhil arora Posted May 27, 2006 Report Share Posted May 27, 2006 I want to make serial communication between two microcontroller using IR.but i donot want to use IR reciever moudels (from vishay) instead i want to use simple IR led as transmitter and IR photo-diode as reciever.to decrease the cost.

nikhil arora Posted June 22, 2006 Author Report Share Posted June 22, 2006 i have done that in very good manner using TSOP1738 as reciever and a IR led driven by NE555 as transmitter. now to send signals you just have to connect the reset pin of NE555 to Tx of 89c51 and that it and write a simple test program.now TSOP1738 is costlier then simple ir-photodiode but 1738 has many features like noise immunity, IR light intensity variation won't affect your link only decreases or increases the range......Now we know we cannot achieve this we IR-photodiode so i have looking for nice ckt to work with using photodiode..... which is not just amplifier or comparator..........
