TSOP1738 ~ SM0038
May should not work because we generate continuous pulse of IR at 38kHz rather than bursts of square wave with gaps.
See dataheet:
The data signal should fulfill the following condition:
Carrier frequency should be close to center
frequency of the bandpass (e.g. 38kHz).
Burst length should be 10 cycles/burst or longer.
After each burst which is between 10 cycles and 70
cycles a gap time of at least 14 cycles is necessary.
For each burst which is longer than 1.8ms a
corresponding gap time is necessary at some time in
the data stream. This gap time should have at least
same length as the burst.
Up to 1400 short bursts per second can be received
continuously.
Ups, my mistake, i wrote vice versa, IR correct pinout :grin:, but see the burst length and the gap time of at least 14 cycles necessary, as in the datasheet.
