Advice on input IR signal threshold value
Tested under sunlight(strong), it is interfered seriously indeed, the distance is too short to be practical. it still works fine without sunlight irradiated directly.  ...

Advice on input IR signal threshold value
I need turn to other way if it is true under sunlight. I'm not hardware engineer, not understand the circuit you gave. How about the max value of  input frequency? can...

Advice on input IR signal threshold value
Brian: Thank you for your explaination,it is very clear. I was confused by the "DC" in "ambient DC irradiance".   It is very clear that source illumation must be increased...

Advice on input IR signal threshold value
As you said,the signal modulated in 40Khz, received and decoded by TSOP4840. For this is a game set for child, the worked distance should not be too long, especially play in...
