hi,
i am building a robotic system...in that the system should be able to sense the object automatically....i am using ir transmiter(555 ic and ir led) and ir receiver(tsop1738)...ir sensor should be able to sense the ir light coming after reflecting from the object...
when i placed the reciever and transmitter face to face its working properly ....but when i placed both facing the same side, the sensor is able to sense only vey near object,about 5cm....i need to get a larger range...when i tested my sensor with tv remote, the sensor is able to sense object at a long distance....so i think the problem is with my transmitter...i also tried to give the 38khz wave from function generator to drive the leds,...i am attaching my transmitter circuit diagram
if any of you a ir transmitter circuit pls provide that to me....hope you will help me in trouble shooting the problem
