I’m looking for a proximity sensor that doesn’t use sound within the 45Hz to 64kHz range, but would work with an arduino without too much issue. Any suggestions would be helpful.
The project I have in mind will be mounted to the vest of a pet, needs to detect range, and work inside and well as outside (so lots of ambient light from sun or modern LED lamps).
The sensor I found is the US-015 and sends ultrasound at 40kHz. But it looks like dogs can hear frequencies from 67Hz to 45kHz while cats hear at 45Hz to 64kHz… so something outside of those ranges, this way it doesn’t bother the pet. Maybe a light emitting sensor maybe?
Ultimately, I’m looking for a combination of sensors to cover 360 degrees, about 6 feet away max distance.
I need it to do the following, in order of priority:
- Detect objects within 2m (6ft. or so)
- Update around 100 times a second or faster
- Not irritate animals with sound
- Reasonably cheap so they can be easily replaced when broken or lost
- (optional) Detect/report distance
Any ideas/suggestions would be greatly appreciated! I’d like to not have to set up reflectors everywhere in order for this thing to work.
