@@robojax Actually, I purchased the GP2Y0A21YK0F (10 to 80 cm) and have it running on a 5V Arduino at about 4.5V. I ran a basic distance program that includes the Sharp library (2.0) and I can't get any data input to the Arduino over 30cm. It the floats at 16mm in the Serial Monitor when no object is present. When an object is present, I only get readings between 9cm and 23cm reliably. I rarely get 30mm. I never see 80cm lol. I read the data sheet, and I see that the output signal is non-linear and its voltage will drop the further out an object is, but I expected to least see the 80cm once in a while. Any idea where you might start to help boost the performance of the 20cm-80cm range of this model? Things I've tried: 1. Different sensors of same model (same result) 2. 100 µF capacitor (seems to smooth output but does not increase performance) 3. Long object obstruction times (the 80cm never shows its face :) Happy holidays! And thanks for any tips! Narci
Sir, these sensor read cm but I searching mm and resolution should be 1 mm and the sensor should be repeatable. No fluctuation. What sensor I should choose ?
Can you please explain why I am getting 74 as continuous reading using GP2Y0A41SK0F, when I am putting it towards Ground. Distance between sensor and ground is around 10 cm.
perhaps that is the maximum range and Arduino is not reading anything and you get maximum. check wiring. use multimeter to read voltage that goes to Arduino.
Thanks for the tutorial. Very helpful. I am using a GP2Y0A60SZLF Sharp Distance Sensor 10-150cm which has GND VCC EN and OUT. The code provided mentions connecting the signal pin to A0. Is the signal pin EN or OUT? Should I only use one of those pins or both? Right now the code uploads but the serial monitor is only reading 0cm nothing else.
Unfortunately I have not tested it. why not test it and ten type your comment here so everyone know if it works or not. I have seen this question more than 20 times now. Thanks
perhaps after watching this video you've learned that we are simply measuring voltage which is representative of distance. I should have video using ESP32 on how to measure voltage or potentiometer voltage just search my channel. Here is how to find Specific RUclips Video in a channel bit.ly/findRUclipsVideo
There is a variable called "dis" which holds the distance, for example if distance is less than 50cm, you turn on something connected to pin 5 do it like this if(dis
Hi Sir, may I ask how do I get the distance in 2 decimal value ? I would like to get more accurate result such as 10.05cm or 10.54cm instead of 10cm. Could please help me , thank you very much.
Hi sir. I am controlling a DC motor with infineon motor control shield BTN8982. The sharp sensor output is connected to A8 because up to A5 shield is covered. But at A8 there is a error. Like 'A8' was not declared in this scope. Why...?
The speed is determined by the delay in the loop. Change (little by little) it and make it smaller (faster) and see at minimum delay you are able to read.

Hello, I am considering using either this, or a PIR motion sensor for my project. I have 3 main questions for you at the bottom of my comment. For my project I will be detecting my cat when she gets on my window sill to eat my plants. I want to trigger a buzzer to scare her off. The reason why I don't want to do a Motion sensor is because if the cat climes up on the window, she will move very slow and I worry that it will not trigger. I would rather be able to control the trigger in my code. If I do this distance sensor, I plan to keep a rolling average of the voltage so that it can trigger if there are quick sudden changes. I do not need a wide angle. preferably a very small angle of detection like 12 degrees and the distance will be less than 2 feet. I have good coding and Arduino skills but I haven't used either of these sensors before. 1) Does this sensor only detect a small field of view straight ahead? (I prefer if it does) 2) Does this sensor require a flat surface, and how large does it have to be? 3) Do you recommend choosing the Motion PIR or this distance sensor? Thank you very much for the video!
Hello Xavier, 1-This detects small field of view, 2- any surface. doesn't need to be flat(have not tested on glass) 3-For your application this would be better.
@@Javii96 Hello, I would like to ask whether it would be possible for you to give the code for my project because i have a similar project like yours and i don't know the code. Can you help me? Thankyou in advance!
@@williamparedes7155 Hello, I would've been happy to share my code, but I still haven't started this project. I've been too busy lately. Sorry, but this video actually shows some sample code and how to get started if you fast forward to about 5:10. What part of the project are you having trouble with?
Stupid question: how do I actually connect the sensor to the Arduino? Like, I have all the necessary hardwares, a sensor, a trio of cables that can extended it and an Arduino Mega 2560, which has a _lot_ of ports and I don't think I understand which cable goes on which port...
You are welcome. Very simple. the word "dis" is holding the distance. below this line int dis=SharpIR.distance(); and change it to int dis=SharpIR.distance() * 10; Now distance is multiplied by 10 to show in millimeter .
@@robojax I did it and I noticed that he only multiplied by 10 without taking into account the number he could have after. I use a digital sensor GP2Y0D805Z0F
I just added the link in the description on how to use 2 or more of this sensor. You could also just search my channel for the word "sharp" and you would see that I move than 4 videos on this .
This code is the simplest and unless you did incorrect wiring or changed the code, it should work. Try checking the wiring and do not change the code. Watch the video without escaping. It should work. You should get some kind of error. In the bottom window of arduino, scroll up and you will see error. Post the error under this video and I will check it for you.
@@robojax The code worked, it was a small issue. I wanted to ask you what would happen if I use the serial plotter for this? Is there any way I could get the voltage as the output?
it depends how fast the robot it moving. If it is slow enough and if you install is high enough and point it down on the front of robot, it should detect end of flat surface and program your robot to take action like stop or change the course of movement.

Hi, You can do it in many ways. The simplest method would be to store the data using MicroSD card module. You store the data on microSD card and later read it with your computer. Here is MicroSD card www.amazon.ca/dp/B0793H4GPC

No problem. I will do my best to reply. I don't have the circuit in hand to test it but it should work. I have provided the manufacturer website with the datasheet. Here www.sharp-world.com/products/device/lineup/data/pdf/datasheet/gp2y0a02yk_e.pdf it doesn't say anything about the angle and it should work.

Hi Robojax, the code you provided ran quite well. However I don't know why the distance is 1cm shorter than actual distance. And could you please show me more in detail how to implement it because I need it for my system identification with accuracy of 1mm. Thanks
if you see consistent 1cm difference, then subtract it . After this line int dis=SharpIR.distance(); dis -=1; this will correct it. But if you get various differences, then there is issue with the sensor.
Can I implement it in mm, what I mean is that when I move the object, the distance will change 1mm for the smallest scale because I want to improve the precision. 1cm change is too big for my system. Thanks a lot
Yes you can. this line gets the value in mm. int dis=SharpIR.distance(); change it to int dis= (SharpIR.distance())/10; 10mm is 1cm, I have divided by 10 (/10) and now you will get in mm. I don't know how accurate it would be in terms of mm.
Well, I met another problem with this sensor. I use Matlab Simulink together with Arduino to implement the experiment. However, I can only get the raw analog value from Arduino and the result is very fluctuate and has lots of noises, I can't read the result even the distance is a constant. Do you have any experience with this kind of problems. Sorry for asking too much. Thank you
No you can't because this can't be directed to a point. You need very accurate beam to be directed. VL530LX is laser based distance sensor but it doesn't have red light to tell you where it is hitting. Here are my videos on the laser distance sensor ruclips.net/user/robojaxTVsearch?query=VL53L0X
Take the screen shot of error and post it on this website onpaste.com/ and then you will have a new URL (address) and share the address here so I look at it.
porque 1 cm es 10 mm, simplemente divídalo entre 10. la variable des mantiene la distancia, así que haga esto debajo de esta línea int dis = SharpIR.distance (); Agrega esto des / = 10;
this sensor can't give you mm accuracy. so you get cm. The decimal point (.) depends on Data Type. See this video to learn Data Type ruclips.net/video/n0z6fjww8eA/видео.html and here is the better video on Sharp which is form my Arduino course ruclips.net/video/4f0UD8O768I/видео.html

if you see consistent 1cm difference, then subtract it . After this line int dis=SharpIR.distance();
dis -=1;
this will correct it.
But if you get various differences, then there is issue with the sensor.
Can I implement it in mm, what I mean is that when I move the object, the distance will change 1mm for the smallest scale because I want to improve the precision. 1cm change is too big for my system. Thanks a lot
Yes you can. this line gets the value in mm. int dis=SharpIR.distance();
change it to int dis= (SharpIR.distance())/10;
10mm is 1cm, I have divided by 10 (/10) and now you will get in mm. I don't know how accurate it would be in terms of mm.
OK, thank you very much
Well, I met another problem with this sensor. I use Matlab Simulink together with Arduino to implement the experiment. However, I can only get the raw analog value from Arduino and the result is very fluctuate and has lots of noises, I can't read the result even the distance is a constant. Do you have any experience with this kind of problems. Sorry for asking too much. Thank you
Can i use this sensor in 3d scanner????plz reply
No you can't because this can't be directed to a point. You need very accurate beam to be directed. VL530LX is laser based distance sensor but it doesn't have red light to tell you where it is hitting. Here are my videos on the laser distance sensor ruclips.net/user/robojaxTVsearch?query=VL53L0X
why can't it be used on wemos d1?
I would have to write library for this. The current library will not work.
@@robojax Sorry, I do not understand. What do you mean?
hi ,,,,,,,,,,,,,,,,dis=SharpIR.distance(); brings me an error
Take the screen shot of error and post it on this website onpaste.com/ and then you will have a new URL (address) and share the address here so I look at it.
Hola Buenos Días. Como hago para que el valor sea en centimetros y no en mili segundos? Gracias
porque 1 cm es 10 mm, simplemente divídalo entre 10. la variable des mantiene la distancia, así que haga esto debajo de esta línea
int dis = SharpIR.distance ();
Agrega esto
des / = 10;
@@robojax Ahhh buenisimo! Muchisimas Gracias! Saludos desde Argentina
De nada. Saludos desde Canadá. Mantenerse a salvo.
@@robojax Hola Perdón por la molestia de nuevo jaja... Me dice que tengo que definir la variable des... Como la defino? Gracias
Is it for cm only Sir?
yes and if you want it in mm then divide it by 10. if you want it in inch multiply it by 0.393701
@@robojax owww okokokok Sir thankyou. Can it have a value of (.) something or it just get whole numbers of cm units?
this sensor can't give you mm accuracy. so you get cm. The decimal point (.) depends on Data Type. See this video to learn Data Type ruclips.net/video/n0z6fjww8eA/видео.html and here is the better video on Sharp which is form my Arduino course ruclips.net/video/4f0UD8O768I/видео.html
@@robojax okokok thank you Sir
@@robojax hello Sir I have another question do you have youtube video about ultrasonic sensors? im trying to find ultrasonic sensor for accurate mm units because i think its more cheaper
Thank you Robojax, but I have a question, how can I have the results in centimeters?
If it is millilitres just divide it by 10. Arduino can do that easily
Des STI2D SIN en projet ?
Désolé je n'ai pas compris
@@robojax In France, at school, we have to do a big project in informatic/programmation (for the levels) ^^ STI2D is the name of this procedure
So, thank you so much for this video ! You help me so much !
too many words, too complex tutorial. this is a simple analog sensor. You no need any library to read it and calculate the distance.
wrong. I've made such videos. We have to explain everything. of course you are welcome to skip and get the code. Good luck.
I need to find someone to help me do this in code..

Hi, I just discovered your comment without reply. This is new feature of RUclips for creators. Sorry.
he is speaking wakanda accent
LOL.
POORLY explained.
Thank you.
