Hi,
I am building an infrared remote control for my project. I'm using TSOP1236. I connect an oscilloscope to the Vout of the TSOP1236. From my visual, there is a waveform on the oscilloscope screen. But the maximum distance before I lose sight of the waveform is 7.5cm or 3 inch. This is very short from what the datasheet said which suppose to be 35m. the current passing through IR LED is more than 0.1A and i also inserted pulse of 36kHz to the IR LED. Eg. i insert squarewave of 36kHz for 560us then nothing for another 560us. and the whole process is repeated again but the range still doesn't increase. the current going through IR LED is quite high and i also inserted pulses of 36kHz not continuous 36kHz. I have done everything said in the datasheet but the range doesn't increase.
Do you guys have any idea to solve this problem?
