Wondering what would work well for a robot vacuum. It will need two types of sensors, (1) for nearby objects and to detect stairs/drops to (2) not fall off of surfaces. I don't want to do #1 with bumping into objects, as I want to avoid hitting fragile things.
Is there a plug-and-play LCD display and controller package to read the range, as you've obviously made in the video. These are such popular units and i don't have the electronic know-how, just want to read the range
I need to measure the clearance between two moving cars with sensors that requires a sensor to be installed on the following car. Which sensor will be best suited to me?
Yes, that is the best we have to offer right now. There are certainly Lidar units with a greater range, but when you start reading thing like "These units are available at bulk pricing of $12,000", you learn to live with 40 meters for a while :-)
Those IR sensors don't measure reflection, they use triangulation to determine distance. So, they are not significantly affected by the color of the object. www.sharp-world.com/products/device/lineup/data/pdf/datasheet/gp2y0a21yk_e.pdf
Im sorry. But what the point of only saying stuff like: "The range is fair, not great but decent... The cost are low. The powerconsumption is high." This is useless since we dont have any reference. Especially since most people watching this video probably dont know alot about distance sensors... Maybe you can give actual 'SMART' ranges.
It would have been nice if you had commented on the field of view for each sensor.
Awesome video thanks Rob! Super helpful!
I see what you did there.
Where do u work now?
I'm striking out on my own to be a freelance content creator :)
I'll try not, but I hear Pete is going for that look, though :P
Good luck to you Shawn! Planning to stay on the UA-cam scene?
@@AdityaMehendale Thanks! I have my own channel with all of 2 videos on it. Time permitting, I'd like to make more for it :)
great thanks for the video... what is the minimum distance measurement with ultrasonic principle????
Thank you Rob, very informative. However, it would be nice if you enable cc button, the subtitle.
Good day! How long is the maximum distance coverage of ultrasonic sensor? Thank you for your response
Can you focus sensor on special kind of objects?
Good job, Rob!
I’d like to see the programming but, it is very good!

Probably best to just use some ultrasonic sensors.
Depends.on ur programing site and what u have to use

Does the IR sensor have any threat to skin or eye?
Can these sensors measure millimeter? It only shows cm
Now we need something to measure distances above 40 meters/yards, which is the limit of the Garmin Lidar (right?)
Yes, that is the best we have to offer right now. There are certainly Lidar units with a greater range, but when you start reading thing like "These units are available at bulk pricing of $12,000", you learn to live with 40 meters for a while :-)

Nice 👍
No Time-of-Flight?
Sonic sound until is affected by the color, try reading a piece of white reflective oak tag paper
Good, but the measurement of ultrasonic really depends on surface ( slip, sharp, ...) l
Awesome!
Wow! Thanks!
ultrasonics sucks in humid or hot environment...sound speed varies with temperature
You failed to cover the most accurate and cheapest distance measurement detection unit on the market; the tape measure. You're welcome.
