  • Muito Bom. Very Good

    posted by xxscorpioxx

    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.
  • Light sensors works great; easy installation

    posted by cosmicray

    The device easily detects motions in its working range. The schematics on the device is very useful, though there is no instruction in English.
    Manufacturer would do a great job if the back of the device was covered by an insulating material.Also, there is no way to attach the device to the wall of ceiling. I managed to do it on the plastic ceiling by attaching it to a special bulb socket that was lacking a bulb.
    Although it's not perfect I highly recommend it to anyone, because it's very useful.
  • 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.
  • good value for IR proximity detector

    posted by ScottJ

    pulses IR LED for best sensitivity to IR detector. Very nice design, simple to use.
    The circuit uses a 555 timer chip to pulse IR LED, which is detected by IR detector. Use 2K pot to tune 555 frequency for best sensitivity by IR detector (around 38khz). Also, the IR detector can pick up IR remote control. It will flash the on board sensor LED indicator. The other 10K variable resistor seems to control power to the flashing IR LED.
    very good value for proximity detection, or sensing IR remote control (but not reading value from IR remote - just that it's on). I would recommend this product.
  • Good economy

    posted by onekit

    Very useful thing. When I come home at evening and my hands are occupied with bags, light turn on automatically if it necessary.
    I think we must use that devices everywhere and it allow us to economy electricity effective.
    I construct it with regular plug and now any device can be connected. In ideal version device must looks like plug and only two wires to sensor. Other wires needn't. Just two plugs father and mother type.
