  • A Basic IR Proximity Detector

    posted by DendoRacing

    Easy to interface to the Arduino. Adjustable sensitivity for each detector allows detection range to be adjusted between 2cm to 5cm. LED indicators on board display detection status which makes tuning and testing simple.
    I was able to use this to build an Arduino obstacle avoidance robot that worked very well in the right conditions.
    A basic four channel IR proximity detector that is suitable for indoor use only. If you need a more robust detector, look for something that uses modulated IR light to filter out other light sources.
  • Good for the price

    It's cheap and it works okay. PRetty easy to wire up - with an Arduino 5V to 5V, GND to GND and Out to a digital pin configured as input. You can connect it up without a microcontroller - basically if you have 5V and GND connected, the out pin gives 3.3V (I think) and apparently has a resisotr in series so you can connect straight to an LED - this is useful for troubleshooting
    Its not mentioned in the docs how to adjust it - if you look at the 2 adjustable bits (variable resistors I believe) they are labelled on the PCB - one is labelled Ch1 and the other labelled RL2. - Ch1 changes how long the output stays on- RL2 controls the sensitivitySensitivity isn't that great so i had it set to maximum
    Good value for money considering the price, if you need maximum reliability you may need to pay more (or maybe get two working together and either one could detect.Would recommend it for hobbyists.
  • Cheap IR Receiver.

    posted by vinra

    0.19 cents a piece it is a very affordable receiver. It came packed in bubblewrap, antistatic bag and in mint condition. 20 pieces will probably last me a lifetime.
    It is a 38kHz receiver and can be used with an IR transmitter diode. The pins looking from the front are.Left - Out.Middle - Ground.Right - Vs.Just google 'Ir receiver' and you will find a lot of useful info on this product.
    I would recommend this product to friends.
  • Could be brighter

    posted by CartDude

    Good build quality, heavy enough to help with the heat management. Nice mirror finish on the reflector, fits well into suitable flashlights. Does not emit much of visible light. Works with 6volts too.
    Good for CCT-camera lighting and IR photography or other needs for infrared light. Use creatively.
    Could be brighter, but all in all a good product.
  • Works great

    Does what it is supposed to do. Gives a low signal when something is reflecting, a high signal when not enouch is reflected. The sensitivity can be adjusted with the trim pot. Easy to connect directly to arduinoo; - to gnd, + to 5 V (maybe 3.3 works as well) Dout to one of the digital pins
    The signal depens both on the distance and the reflectivity of what passes. IE a more reflective item will be detected at a larger distance than a less reflective item.
    If you need it (or think you can have some fun with it), go for it.
