hi. Why is the analog output so spikey? Hard to get clean readings on even a multimeter. Is there a way to correct? I can’t seem to find any other graphs or info on this. Bought it for the analog output as it suits needs better. Any further input helpful. Thanks.
Hi,
How do you power the URM V4.0 ? Did you verify if the regulated 5V supply to the UARM is stable ?
Regards,
Thanks for response bdaouas. Yes. Solid 4.99v to sensor. Thru testing with digital and analog meters I get same results.
The sensor Spikes about 1.5-2.3v during closer/further movement.
It doesn’t seem to be any rhyme to it.
Also, perhaps another discussion, servo control pin is merely mentioned in manual. Would like to know the logic of it and how it interfaces.
Hi,
Did you try the sensors with a microcontroller ?
We unfortunately don’t have more information than the manufacturer’s Wiki page about the servo control pin.
If you have connected the URM V4.0 Ultrasonic Sensor to a microcontroller and you have trouble getting correct distance readings, please contact us on our Support Center referring to this post.
