Photo Interrupter GP1A57HRJ00F

sku: SEN-09299 RoHS Compliant

Description: This sensor is composed of an infrared emitter on one upright and a shielded infrared detector on the other. By emitting a beam of infrared light from one upright to the other, the sensor can detect when an object passes between the uprights, breaking the beam. Used for many applications including optical limit switches, pellet dispensing, general object detection, etc. Gap width = 10mm

A breakout board is available.

    Snapping the alignment pin off the bottom of this thing is very easy and is required if you want a flush fit against the SparkFun breakout board.

    if i use 2 off thes could i make a crono to take the measurements of and fps of a small object with the arduino uno?

    Going to pick up a few of these to detect if the front door of my motel is open. I was going to use a hall sensor or laser trip beam, but this one is shaped just right. Just need a small protrusion on the door to break the beam when the door is closed, and un-obstruct the beam when the door is open.

    Would you consider carrying a photo interrupter with a narrower gap? This gap appears to be almost 0.5 in. I would like one that is twice or thrice as wide as a PCB (so I can use PCB material and the interrupters to make a quadrature encoder.

      If you’re going to be making PCBs anyway, you could make a PCB with these spaced however far apart you need. (They were commonly used in old ball-style mice).

    I just got round to using this with the sparkFun breakout board.

    my issue is that it doesn’t seem to be sensitive enough.

    I’m trying to detect a drop of liquid falling and it doesn’t want to trigger the sensor.

    Is there any way to increase the sensitivity, I used a 220 ohm resistor on the board and am wondering if a different value would help me.

    Any ideas?

    Cheers.
