Hi,
I'm using a PIC16C508A to transmit/receiver I.R. pulse (negative width pulse=5ms and positive width pulse=200ms).
The circuit board receiver IR no problems w/ absence light, but I've problems w/ sunlight and lamplight incandescent.
The receiver IR phototransistor w/ filter IR.
 
What's the problems ? Any suggestion ?. 
 
This is circuit attached.
 
Thank you.
