  • works well if there is no IR interference

    posted by DonQuijote

    adjustable range, via screwcomes threaded, and with locking nuts, so it can be attached easily anywhere
    i wanted to put 2 of these in a doorway to detect which way people go through. It was VERY tricky to mount and adjust their sensitivity such that they don't influence eachother.
    i suspect its just a ir led, and ir phototransistor with additional op-amp, or transistor based circuit.You could easily make yourself one from cheaper parts, but designing/printing such a versatile case could raise the price, even without taking into account the time for designing/producing it.For simple tasks, in controlled enviroments without ir interference, it is great.
  • Good item

    PriceEasy to installGood reception of movementCan be build into custom housing
    Missleading information about light timeout. But can be adjusted if you are skilled with soldering gun. (see forum below)Default delay of this sensor is aprox. 40 seconds.
    Good item for this price.I'm using it as light switch for my hallway and I'm very satisfied. I managed to build it into ceiling and sensor is almost invisible and nicely fit into ceiling.
  • Very good price

    This is a very cheap sensor considering its usefullness.I am using it with Arduino to make a line follower robot.
    Using it trough analog reading it gives a fair enougth value from up to 5 mm of a black tape on a wood or clear keramic floor.
    I am very happy for my purchase.
  • perfect for near object detection

    posted by Joost.de.Greef

    Small, convenient package. Works as advertised. No problem detecting any object with 2 cm range, but you do need to compensate for ambient light. This is easily done by collecting the value twice, once without the IR-LED on, once with the IR-LED off.
    The datasheet is readily available on internet, maybe DX could put a link up? for instance www.vishay.com/docs/83760/tcrt5000.pdf?
    Excellent item, I'm going to order more.
  • Ótimo produto

    Easy to use, although no instruction manual, compact and inexpensive. Recommended.Fácil de usar, embora não tenha manual de instrução, compacto e barato. Recomendado.
    For those who do not have such a hurry so worth it because it is a great product at a price that will not be found easily. Much less here in Brazil.Para quem não tem tanta pressa assim, vale a pena pois é um ótimo produto a um preço que não será encontrado facilmente. Muito menos aqui no Brasil.
