Hi All ,,
I want to convert the signal received by IR Receiver Tsop1738 to steady output level for example 1 if there is ir signal 0 if no Ir signal received(an object cross Ir beam).
the signal received by the receiver as the following:
>>as you see in figure above the received signal is square wave 32hz(2ms off/29ms on).
>> if there is no signal received due to object cross the ir beam the output of the tsop1738 goes high and still high while the object cross the beam.
>>I see i can do what i need using 555 timer and other ic's like 74123 but i don't want to use them
>>minimum time for crossing the beam 20ms.
>>The transmitter circuit
as you see the circuit send 38khz for 2ms and off for 29ms.
Regards
