Hi everyone. I jeep running into an issue of my sensors not pumping far enough to detect anything past 50CM and I'm also getting a lot of false flags. Can anyone give me info as to where I can find sensors that are reliable and high quality? Thank you!
I bought mine off Taobao and results are fine.
There may be multiple manufacturers of the same thing, I'm not sure, but they all look identical. If you have an HC-SR04 and it doesn't perform beyond 50 cm there's probably something else wrong.
It's not a good sensor. Spend a little bit more money on a better ultrasonic sensor.
You could try this. works well
I use this one http://www.auselectronicsdirect.com.au/arduino-dual-ultrasonic-sensor-module - it works well just is sensitive to heat when wiring
