  • I have this sensor. It's nice and does indeed have a pretty good range of several feet (I've reliably gotten 3-4 ft). There are 2 caveats. At short distances (<4-5 inches), the output goes low, and then when it gets within range, it goes high....then it gradually decreases as the distance increases. This means that there is a sort of discontinuity between 3-5inches and 5+ inches.

    The second issue is that the values greatly based on the object in front and angle (ideally you need a reflective hard white surface facing straight-on). This just makes it a little hard to calibrate for some applications.

    Overall, MUCH better than the ultrasonic ping sensors, and way better than trying to build your own IR/Phototransistor pair.

No public wish lists :(
