Infrared detection

  1. Apr 15, 2010 #1
    Dear Experts, o:)

    I bought a pair of infrared LED and a receiver or detector (not sure the proper term or if there is any difference between these 2 terms) but the seller does not know what model it is and does not know the pinout of the detector or receiver.

    What i could find on the net that has a similar appearance is this :
    http://www.hvwtech.com/products_view.asp?ProductID=473 [Broken]

    I like to confirm that the for this design of infrared detector or receiver, the pinout is always the same , as in Pins : 1(Vout), 2(Gnd), 3(Vcc) .

    But there are other designs with different pinout configurations from one another, namely:

    A : pins : 1 (Vout), 2(Gnd), 3(Vs)


    B : pins : 1 (gnd) , 2(Vs), 3(Vout)
    There is another datasheet : http://www.digchip.com/datasheets/parts/datasheet/513/TSOP31238-pdf.php

    Is there any other way to find out about the pins without damaging the sensor?

    Thank you for reading.

    Ramone :)
