  • 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.
  • 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.
  • 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.
  • 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 Sensor

    •Good build quality!•Better price!!•Free shipping!!!•I checked the sensor range up to 50 cm and working properly. I have not tested the limit of 80 cm indicated in the product information.•The sensor has a screw in the back to adjust the detection range•A red LED on the back lights up when an obstacle within its range.
    •The sensor's detection distance varies with the color of the surface which reflects light. In a dark surface, the detection distance tends to be shorter from the initially set.•Include some terminals on the wires would be a good idea.
    •The device does its job at an unbeatable price!
