Lesson 77: Measure Distance with VL53L0X 6 pin Laser module with Arduino

[@ljubomirculibrk4097]

Real deal, works whit mega from the start. Thanks

[@davidcastellanos2887]

Thanks for that amazing video, is very helpful for me

[@robojax]

Glad it was helpful!. Please subscribe. I appreciate it.

[@AnundaChuenlerssakul]

Hello Sir, Thank you for the informative video. I have a problem when I try to use A4 and A5, the data is not send to the monitor screen. Do I have to specify any pin declaration if I directly use analog pin instead of SDA and SCL pin?

[@Arjun_Vasudevan]

After adding the VL53L0X library, the word Distance gets coloured for you but it doesn't for me, why is it so ?? I have the same library as you have

[@robojax]

Dot worry about Color. What important is if it works. Just close Arduino IDE and open it and see.

[@contrarian8870]

The specs only give the max range. What's the minimum distance you can read?

[@robojax]

I have updated the page where the code is robojax.com/learn/arduino/?vid=robojax-VL53L0X Datasheet does not mention the minimum distance, I have included image of page 30 of datasheet where you can see the angle between emitter and collector (two small holes) and see the distance and find out at what minimum distance the collector receives the reflection from emitter. good luck.

[@ignacevandevelde2733]

Hi man, it's clear and helpfull! In the begin the wiring was my problem, because I'm a fully blind person thats playing with arduino to make my own solutions to have access in my life to to things myself. I use this distance controller on my drone MJX Bugs 5W to fly independently in my own garden. CAUTION, doe not flying blind with drones before you've trained verry much times in a school or with other good trained pilots!!!! Thanks for sharing this demo and explanation here! Helpfull, go for other and many demo's here plz.!!!

[@robojax]

You are welcome. good luck with your project.

[@blackdessert1979]

i had problem with this sensors. i need to measuring 50.25mm but this sensor show only in integer value

[@robojax]

Of course you should have problem. The resolution is 2mm.

[@ezrakoper]

Will the new i2c address remain after turning power off and on?

[@robojax]

Are you planning to change the I2C address and use the module somehwere else? if not I blive it won't work. Using Arduino/Raspberry Pi, once the program starts, the address is activated and is there until you shut it down. you won't be able to use the module until you power up the board and run the program. I looked at the datasheet again and it confirms my understanding that it deos not save the address. www.st.com/resource/en%20/datasheet/vl53l0x.pdf

[@ezrakoper]

@@robojax thank you for the reply. I was considering using several to measure distance all around, kind of lidar. The other option is to place a single one on a motor and make it spin while keeping track of the angle in some way. So I just play with this idea in my head thinking which direction to go.

[@seismocraft]

Hi , i am using this sensor in one of my projects but I can't get it to work it just shows the same number again and again.

[@robojax]

Hi, you must have changed the code or the sensor is on the exact location. Use I2C scanner to check if you are getting an address for I2C scanner. Search for Robojax.com for the scanner

[@HuyVo-qu7jg]

hi it's very good. but can we use measured signal to control stepper motor? For example, the sensor always keeps a distance of 70 cm from the object, if the distance changes, the sensor will detect and control the motor to operate to keep at 70cm. i want to make Z axis auto. whether it is possible. do let me know.

[@robojax]

Hi Sure you can use it. Hi as the sensor to measure the distance and write your code to do anything you want. Arduino bus for that purpose

[@HuyVo-qu7jg]

@@robojax can you make a video like that, I don't understand much about aruino so I can't do it. thanks.

[@guillermomejiacisneros4304]

Hi, could you give me an idea of what to do, i am meassuring Fuel level with TOF sensor, It works perfect when engine Is off, but when engine Is on, it emideately the TOF get off, like if the sensor were in short. The investigation show me that the spark of the spark plug Is cousing the failure. Do you have an idea of how to avoid this failure?. I already used a shielded wire with no results.

[@robojax]

Hi, yes. it is the noise of DC supply. Put 100µF to 470µF with 1nF capacitor on the 5V and GND of this module. it should filter it. The noise is messing up the i2C signal.

[@marusosaassi5898]

Hi robojax, I want to ask you a question please. I bought an VL53L0X online and the "VCC" pin is named "VIN" instead, do you know if VCC and VIN are the same? can I still connect the VIN pin to 5V? thank you in advance for your time and for the video the pins my sensor has are "VIN, GND, SCL, SDA, GPIO1, XSHUT"

[@robojax]

Vin and bcc are the same

[@marusosaassi5898]

@@robojax thank you so much!!!

[@RonFreimann]

I wonder if this sensor works on liquids as well? Water, oils etc.

[@robojax]

I have the video, a simple search revealed this kzbin.info/www/bejne/qmKXnaxtjpVspas and i checked the link was already in the description

[@pekka2566]

hi do u know how i can control stepper motor with this sensor... please make video for that :P clockwise and counter clockwise depend distance..

[@robojax]

You can get the idea from this video kzbin.info/www/bejne/gZekn4idlrh3o6s

[@NailYusupov]

Hi, thank you for your work. Please help me to fix the problem: when a distance to the object is greater than maximum value (1500 mm for my VL53L0X) it shows random incorrect values much lower than even 1000 while RangeSatus != 4, so I can't check the out of range state. Is it possible to correct this problem? And another question: is it necessarily to remove that red film from the laser chip?))

[@NailYusupov]

Seems that protective film was the cause)

[@joao4181]

Does it read integers only? Floating numbers, right?

[@robojax]

Because the resolution is in mm, yes only integer. it wont' be able to show 0.2mm.

[@ilretaggio2]

why you use arduino to powerup the sensor at 5V if the voltage of sensore are 3.5V Max ?

[@robojax]

then it should be connected to 3.3V. I might have mistaken.

[@ilretaggio2]

@@robojax Sorry i have another question: with your code, my sensor (the same of the video) when start to read, print a value majeure than 50mm of the real measurement. Do you know why ?

[@DzulFahmi11]

i just have vl53l1x, can I apply that program and wiring to mine?

[@robojax]

I am not sure if it works. You would have to download the datasheet and see the difference in registers. Registers are small memory where the values are stored.

[@jimgt3716]

Im not able to compile the file because im prompted "VL53L0X.h: No such file or directory" and I have already included the library

[@robojax]

You did but Arduino did not find it. Click on Sketch->Include Library->Add .zip library and brows to the zip file. It should work.

[@omkarlubal6799]

Use this library: github.com/pololu/vl53l0x-arduino Instead of Adafruit.

[@jakubstejskal6806]

I can measure only between 50-140mm. Any Hint?

Thank you! It seems to have difficulties to recognise the D12 on the Arduino Micro (it's written ~12 on it) even tho there is no error message. The distance measurement only shows -1. I tried to change the pinMode(12,INPUT_PULLUP); , digitalWrite(12,HIGH); to another pin but it didn't work. The code seems to works on the Arduino Nano and a Arduino Nano Copy both with D12. Could you help me?

They both are the same sensor (chip). Just the module has different color or number of pings. I made different videos to make viewer comfortable knowing the module ibn video is exactly the same .

[@redreska6311]

Hello mate ! I need your help in this case ! I want to detect distance between 0 to 30 mm with variation of 1 mm. I tried Sharp GP2Y0A02YK0F and GP2Y0A41SK0F etc .. but they are even non linear as mentioned in datasheet ! or sensibility is low ( 1V / 30 mm ) ! I want to see the curve of this sensor ( Voltage / distance ) to know is there a linear part of the curve with good sensibility ( expl 2 V / 30 mm ). Please answer my question, thanks !

[@robojax]

Hello, this is totally different. Sharp modules output voltage proportional to the distance. this module however does the calculation internally and stores it in digital memory called register. then we read the register to get distance. this is very accurate with ± 2mm as mentioned in the datasheet.

[@redreska6311]
