Review on Infrared Reflective Photoelectric Obstacle Avoidance Sensor by HiLetgo by Brent Porter
Good but only for close-up
Can't see objects more than 10cm away or so, although it claims it can work up to 30cm I've tried screwing it both ways I knew when I bought it that it would return a digital output, but it would be nice to have a version that returned an analog output so you could write distance dependent code .
- Confident
- Out of fashion
