  • At first I could not get this device to work -- the SparkFun Inventor's kit sample code always came back as 0.11 inches no matter was in front of it. I contacted customer support and they asked if I was in an office setting with fluorescent lights and/or HVAC nearby. I had both overhead. I took everything to another room without LED lights and no HVAC, and the device worked perfectly. Apparently, things can interfere with the ultrasonic sensing.

  • I had a project where I really needed a reliable sensor, and I found that the HC-SR04 had too many bad readings. I switched to the PING))) sensor, which I agree was significantly more expensive, but it worked consistently. I never once had a problem with it.

No public wish lists :(
