Hi,

I need to increase distance using the  Infrared Receiver 
(Item code 350-00014)  with the Parallax IR emitter.

When I use that sensor with a Basic Stamp I can detect
an object at about 3 feet (max) , but the same sensor
with the SX 28 is about 2 inches only.

How can I increase this distance using SX28 microcontroller?

Thanks, Mark

 PS:
Please see the rutine:






DEVICE          SX28, OSC4MHZ, TURBO, STACKX, OPTIONX
FREQ            4_000_000
 
PROGRAM Start
 
INI:

DO
   FREQOUT RB.1, 10, 38000       'RB.1 OUT LED IR       
   IF RB.2= 0 THEN                        'RB.2 OUT from sensor IR    
   HIGH RB.0                                   'RB.0 LED INDICATOR
   PAUSE 500
   LOW RB.0
   PAUSE 500
   ENDIF
LOOP
