Hi. i need an Ir object sensor. For this i designed receiver and transmitter circuits. Transmitter circuit will produce continuous Ir pulses. When an object comes in front of sensor, it will reflect IR light to the receiver. When receiver detect Ir signal, its output will be low (logic 0). I will connect the output of receiver to microcontroller.
My problem is, when i put an object in front of sensor. The output of the receiver is not stable. I obtain a square wave. I want to obtain a continuous low level signal for microcontroller. How can i do this? Do you have any suggestion?
Best regards
