Lesson 77: Using VL53L0X 200cm Laser Distance Sensor | Arduino Step By Step Course

[@bgolfy]

Thank you for that clear explanation! For once, clear video without annoying music!

[@visheshsaxena6199]

very nice video! the best way of teaching online step by step. Thanks!

[@robojax]

Glad it was helpful!

[@rolandwiberg1555]

about the spatial resolution, what is the diameter of the beam hitting the surface ?

[@2007xoxox]

Awesome! You are incredible man!

[@jomfawad9255]

can this be coded that if distance lower than 20mm 5 servo move to 1800 and if distance larger than 20mm move back 5 servos to 0?

[@robojax]

yes and that is very easy. I have tones of videos on servo. most on push buttons with some kond of conditions. just use you distance instead of push buttons. search my channel for servo.

[@AnthonyWebb7]

If the wall is at an angle to the sensor will it still be able to read the distance? Ultrasonic sensors have difficulty unless they are not pointed straight at the wall, curious how these perform?

[@robojax]

Hi, yes for sure it will read the distance.

[@justinekamilay1006]

how can i download the zip library? i clicked the link on ur website but 404 not found for the zip

[@robojax]

Hi, thank you for letting me know. I just fixed the links. you may try again now. salam

[@prathamdeepsingh8210]

Is it necessary to add that 100ms delay at the end of the code??

[@robojax]

I belive not. I did add it to print the value on serial monitor.

[@shailsh3965]

Fantastic Tutorial. I wish to have your expert advise. Can you please suggest which sensor will be best for measuring distance outdoors and is weather proof for obstacle avoidance?..Thank you very much in Advance

[@digitronix532]

Will this work in sunlight

[@jitendrachaudhari7222]

How can output activate when distance is less than specific value? Thanks

[@robojax]

That is called taking action. I have explained it in many videos. You can learn it from this video showing when temperatures reaches certain temperature or goes up or down kzbin.info/www/bejne/fIi1iH-wgKuZaZosi=hHCtvj_gnphhvyGM

[@GameMakerEU]

Could it work with raspberry pi pico?

[@robojax]

If you write your code, yes.

[@markgma]

This video is very helpful. I can use this sensor and detect the distance correct. I found there is an issue: after the sensor cannot detect the distance (namely, it returns 8990) for a while (e.g. 30s), then the program dead. I have to restart by clicking Reset button. Wondering how to avoid this problem?

[@robojax]

It should not die. Perhaps the wires get disconnected. Check them. Leave it without touching and see if it stops.

[@markgma]

@@robojax you are right. the dead was from the loose plug. BTW, the sensor seems not be able to detect 3x3x4" cube if it is 27" far away from the sensor. Thought it might be the object is too small? Do you have any suggestion? Thank you in advance.

[@KRZAKOWY]

i have "Distance: 65535mm TIMEOUT " problem. help

[@robojax]

It seems dead module or bad wiring. Use I2C scanner to check it. The I2C scanner code is on the Robojax website

[@KRZAKOWY]

@@robojax wiring is good, I2C scanner detects address.

[@vrqntln]

Excuse me sir, I want to ask. I'm trying to make it at home. why the output is not up to 1000 mm? only up to 800 mm and immediately jump to 8190 mm.

[@robojax]

You must have the object located at that t distance or there is reflective item.

[@vrqntln]

@@robojax thank you sir, i will try. by the way, can i use VL53L0X to measure distance vertically?

[@deniszorila5055]

Is it possible to have an accuracy greater than mm?

[@justinc2633]

if you want micrometer level accuracy youre going to have to spend more than $15 lol, although i bet if you were to take an average from the readings it would be a lot closer to the real number

[@johnathan7704]

Which is the cheapest ToF sensor you know of? No need for long range, not longer than say 20mm.

[@robojax]

VL1860 is cheap and for about 50vm

[@johnathan7704]

@@robojax thanks! I can’t find this sensor when googling however. Can you link some source?

[@Vhariharan69]

Is this sensor can measure black colour

[@robojax]

It does not measure light.

[@irwankusumah4943]

Thanks for your video, But i have a mistake measure for used that sensor. I hope you can help me.

[@robojax]

you mean you are getting incorrect reading? remove the sticker from the sensor. there is a plastic sticker on the sensor.

[@xvolodea]

Thanks for your nice videos. Can you explain in a short video how work the radioaltimeter that mesure distance till 1000 - 1500 meters ? What are the components and its parameters to be able mesuring such distace. I know hardware in this case are expencive but just an explanation please. Regards

[@robojax]

1000m? wow that is kind of industrial high end range finder or altitude. You might be able to Big/Google it to find read-to-use device.

[@stlo0309]

thanks a lot!

[@robojax]

You're welcome!

[@paparidas2331]

Sir, How many sensors can we connect to a single arduino uno?

[@robojax]

128 sensors via I2C and I have video search for it showing 2 sensors

[@robojax]

Search my channel

[@OTWSkripsi]

I think the sensor's only can measuring about 127cm and than the value Will be 8190... It's not until 200cm, sure?

[@robojax]

I believe I have shown the datasheet for VL53L0X. it says 200cm.

[@justinc2633]

it probably only reads 200cm in a dark room against a white surface

[@dmestr]

Actually, do not understand how it measures the distance directly. Probably it measures the time and multiplay with speed of light?

[@robojax]

that is not our focus. Yes the laser beam hits the object and returns and the time it takes to return is divided by 2. I have provided datasheet if you want to learn more about it.

[@harikrishnanmk5724]

hi where is that zip file

[@robojax]

Hi, links to the resource page in the description below the video.

[@hindi2053]

Its very detailed tutorial. Question: How the DATA and CLOCK are initialized to A4 and A5 of Arduino in your code?

[@robojax]

It is I2C protocol that Arduino assigned .
