Hello
From my understanding this TSOP(from datasheet) should detect only 30 kHZ frequency,but i noticed when i point a TV remote control on it and push a button it also detect freuqency of 38 kHZ(TV remote frequency)-my green led lights up.Is this normal?? Is there possibility to prevent detecting signals of 38 kHZ, and detect only 30 kHZ??
I connected TSOP's leg 1 to ground,leg 2 to 5V. Leg 3 is connected to green LED,green LED is connected to 390 ohm resistor,and resistor is connected to 5V(series connection between leg 3 and 5V with resistor and LED)
