    even the detector is starting to glow..
    ..never experienced anything like this..and no it shouldn't glow.Detectors don't glow.Try another piece.Also remember when buying IR emitters/detectors,buy around 5 to 6 pairs...allows for testing.

    The link which you mentioned uses the TSOP1738 infrared detector..note that this sensor receives /detects only around 38 to 40Khz frequencies ,which means you need to generate such a frequency[using a 555 or a micro] costs aroun 30 to 40 bucks
