Thus the output of the comparator (LM 358) goes high and the LED starts glowing. When the IR receiver receives a signal the potential at the inverting input goes low. Thus the output of the comparator goes low and the LED does not glow. When the IR receiver does not receive the signal the potential at the inverting input goes higher than that at the non-inverting input of the comparator (LM 358). Here operational amplifier (op-amp) of LM 358 is used as a comparator.
Since this variation cannot be analyzed as such, therefore this output can be fed to a comparator. The output of the receiver varies depending upon its reception of IR rays. The transmitter part of the sensor project is an Infrared (IR) Led which transmits continuous IR rays to be received by an IR receiver.
