infrared sensor switch Customers Reviews

  • Good item

    posted by Fixx

    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.
  • For the price it's a great purchase, well built.

    Might be very nice for a home project with your arduino board. The quality is really nice, for the price I couldn't imagine such a nice product. If you need it, buy it.
    Might be nice to use, but till now it's unuseful.
    If you know how to use and for what you should use, purchase it, otherwise, you can purchase it too, it's too cheap!
  • 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.
  • Muito Bom. Very Good

    Funciona como esperado, boa qualidade, estou muito contente com a minha compra, já estão a funcionar num circuito que eu construi.Works as expected, good quality,I'm very happy with my purchase, , I have been running a circuit that I built.
    Faltou uma peça, apenas vieram 9 em vez das 10 esperadas.He missed a play, just came 9 instead of the 10 expected.
    nada a apontar, recomendo a toda a gente que precise deste tipo de sensores.nothing pointing, I recommend to everyone who needs this type of sensors.
  • works well if there is no IR interference

    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.
