SparkFun SEN-00241 Infrared Emitters and Detectors Pair

Side-looking Infrared Emitters and IR Detectors. These simple devices operate at 940nm and work well for generic IR systems including remote control and touch-less object sensing. Using a simple ADC on any microcontroller will allow variable readings to be collected from the detector. The emitter is driven up to 50mA with a current limiting resistor as with any LED device. The detect is a NPN transistor that is biased by incoming IR light.

Datasheets:

  • IR Emitter (Yellow or Black dot) or the internal layout matches the third image above.
  • IR Detector (Red dot)

Applications:

Sold as a pair, with one Emitter and one Detector.

    I had to make an infra-red photo-interrupter for a tacho I’m building. This pair were made for each other, are small, very precise and work beautifully – very easy to build into a reliable and functional system.For very precise work, I rate these two as

    Pretty good, though due to the design the IR does spread out so keep that in mind. Oh and keep a little note of which is the emitter and detector close by, found myself mixing them up often but that may just be me 😛

    I’d found the IR Tx/Rx pair from an American company, but was much happier to find a UK based reseller.
    The IR pair were just what I needed to mend my Roomba. Even with my ham-fisted soldering.
    And to top it off the package came with a small bag of sweets(no idea why) and they were very tasty :D.
    First class post cost more than the components, but it still works out good value.

    These units work very reliably and are very easy to use. I haven’t tried the free sweets yet!
