    Hello All,

     

    I am trying to build the bidirectional visitor counter for my project as in – http://www.engineersgarage.com/microcontroller/8051projects/Bidirectional-visitor-counter-AT89C51-circuit

     

    Does anyone know what is the component code for the IR Transmitter and Reciever LED’s?? 

     

    Also if someone can explain the design part of the sensor circuit, would be highly appreciated.

     

    Regards,

    Bhaskar
