    The circuit will be focused on detecting object (refer to intruder) moving through it using one infrared transmitter and one infrared receiver. When the infrared signal is being blocked (when intruder walk-by) or the receiver does not received infrared signal, the relay will be turned on and thus triggering the buzzer and LED light.

    Any circuit or webpage about this? Please help. Thanks

    Why did you send me email? Like most of us, I will not solve your problems over email, especially when I have not even ever talked with you.

    This forum is public so that others can learn too.

    The pin out is given on the second page of your datasheet.

    basically the three pins are Vcc, ground, and signal out.

    You tell me

    I counted the pins in the schematic and in your datasheet. You do the same and tell me if it can be used.
