Your explanation was easy for me to understand. Thank you for putting out videos like this. Now I want to get some strain gages and try to use them in projects.

@dee5556 4 года назад

Thanks for this video and web page. I'm currently working on a mostly 3D printed bench-top dynamometer with a Nextion Enhanced touchscreen and a Arduino Pro micro. Features include volt meter, amp meter, tachometer, 10A relay, 10Kg load sensor, a geared stepper (to control the break from the touchscreen) and a buzzer. I was trying to work out how I would incorporate a calibration sequence into all this. This was the most helpful video i found. Many THANKS!

I've made a few bicycle power meters using strain gauges. I use a simple amplifier and the Arduino’s own ADC, very basic but actually gives decent power data when set up correctly.

@ivekuukkeli2156 15 дней назад

When you need twisted pairs, you could use LAN cables disassembled. Each cable contains 4 very well twisted pairs. If you need longer cables, you can use RJ-45 connectors !

@HermannKerr 4 года назад

Thank You - I have the idea for a project weighing seems to be the easiest way to measure. Your explanation was excellent - Thank you I am just learning about Arduino and it is simple enough plus flexible enough to handle my project. It is to easily measure volume (via weight) and control the temperature of water for a mash-lauter tun.

@ahmarrana9732 3 года назад

@vickyj7907 3 года назад

Good job. I think you should choose a thicker wooden base. This one is thin and thus some of the strain or deformation is occurring in the base. This can lead to a lower reading on the device.

@zarulzakuan6679 4 года назад

Thank you for this awesome video! How does commercial scale works without initial calibration? How do we make the scale more accurate say I want to measure how much gas left in a tank, which the accuracy of even 1gram is important

@mohitgola7429 2 года назад

Hi, this video is really helpful for making a load cell. I am interested in measuring the deformation of a metal sheet using a similar setup. Can you please guide me a little bit?

@kwakeham 4 года назад

For most average users with arduino background this is a great tutorial. Your gage handling practices in this video and adhesive info need improvement. The HX711 also has many issues with it's reading due to it's overly simplistic and antique architecture. A MUCH MUCH better BoB uses the ADS1120 or ADS1220. These are by FAR many orders of magnitude better be it more complicated. Selecting STC code, bridge arrangements, creep code, dealing with thermal issues (passive, manual, active) material installation, compensation for temperature range, gage protection, and more as well as proper gage installation techniques (glue dependent).

@cthulpiss 4 года назад

any more info on non-HX711 solutions ?

@dee5556 4 года назад

Do you have any suggestions on how to incorporate a thermistor into the scale sketch to compensate for thermal creep?

@lesp315 4 года назад

Thank you the fantastic instructions. Do I understand correctly that you used HX711 instead of Wheatstone bridge? Can I use Arduino Nano for the same project?

@sameerUNO10100 4 года назад

wow cool project ill try it sameerUNO from Twitter

@muzammilmueen3487 5 месяцев назад

@electronoobs Great video. What did you mean that the accuracy can be improved by 'more measure loops' in the code. Can you pls explain ?

@amirohad3765 4 года назад

For the load-cell setup with a panel attached to it: is there a difference in the measured force depending on where on the panel the force is applied? The force I am measuring is very localized (small contact area), not vertical (not a scale), and is very weak (tens of mg), so I will need to compensate for such a difference if it exists.

@rahulpatil303 2 года назад

hello sir, Thanks for this video. really help-full. I have a question in this video the reading in LCD showing only of weight can you please share the video, Reading of Force how it is applying. It will be really help-full. This video is really awesome form most of the other video i got it. Many thanksss !!!!!

@ChandrashekarCN 9 месяцев назад

how to measure continues. or can we put weight and don't take out or what happens if we. example : if we put under water tank and measure, how long it working.

@noemurr1779 3 года назад

Hello, great video, but I have a question: is the wheatstone bridge on the pcb or is it attached to the strain gauge? Thank you

@user-vn4gb5hg1i Год назад

Hi dear great video, I have a question for you, do all load cells connect to the same HX711 sensor or does each weight have a different sensor according to its weight?

@siddharthmali5841 4 года назад

Great

@OnnieKoski 3 года назад

Do you think a CNC digitizing touch probe could be made using these?

@maxximumb 4 года назад

I wonder if you could get any force measurement from a regular resistor?

@CuriousCat-yl8by 3 года назад

Hello! I am very new to electronics, and I was wondering if we would still need a separate ADC unit if the microcontroller itself already has one? I keep reading that standard arduinos tend to have them built in... would you connect it straight into it?

@psychomoust896 2 года назад

My lecturer sucks teaching his class and he's happy that Pandemic prevent him from having to conduct the Lab lecture. I have obtained good sound knowledge from your video...thanks a lot mate!

@5620507563 3 года назад

for the 4 load cell setup with 1 load cell in each corner, how accurate is it when it come to weighing multiple items. like for example, what if there are like 5-10 items on the scale and the items are spread out all over, like some items are in different corners and some in the middle. Will this mess up with the total weight reading or will the scale be able to measure total weight accurately even with items spread out all over the scale?

@King205 4 года назад

Thought this was a great Scott video at first lol

@nollaigbutler7505 3 года назад

This is used to calculate a bending force as the material elongates and deforms, Would I be correct in saying the this could be used to measure a tensile force if it was applied parallel to the gauge instead of perpendicularly like in the video

@yeshisingye5089 Год назад

What is caliberated load and how can we calculate it to put it in the codes

@blue-vq4xg Год назад

with wich colposant you've converte the résistance of the gauge to the voltage please ?

@amaanullahkhan 2 года назад

can a load cell coupled with servo motor, or I will need an AC Motor to work with a Load cell (Strain)

@HannyDart 2 года назад

whats the name of the white glue you were using? :)

@mohammadhoutary1338 4 года назад

Can the keypad be added to the project to add the item price and multiply it by weight in kilograms 🌷

@avibank 4 года назад

Did you need to amplify the signal with additional components when using the strain gauge? I've also read that using more than 1 strain gauge can reduce error (for example, configuring 4 of them in a wheatstone bridge). Might be an interesting video.

@kwakeham 4 года назад

While the HX711 I generally regard as fit for the trash, it does have a built in programmable gain. This combined with it's old sigma-delta design gives generally better quality and less noisy data (SAR uses sample and hold, Sigma-Delta "integrate" over time). There are many many strain gage configurations depending on what you are mechanically trying to sense. Poisson setups, bending arrangements, differential beam arrangements, etc. Each using multiple strain gages. Search Omega Strain positioning PDF for a quick reference.

@antonrimsky7128 2 года назад

Hey, great job 👏... it's so fascinating:) I have a question, is it possible to identify the position of objects using the same sensors?

@3dfreedom316 8 месяцев назад

Im sure it would be possible in at least one direction as strain increases linearly so as long as you know some basic info it would just be simple math

@mertgulcurgs 4 года назад

@raknin 3 года назад

Hi How could i measure force in newton/meter using the strain guage?. What component i need to convert the analog voltage to newton/meter (force)?

@djokinac 3 года назад

Greeting I have one question and maybe two :-). I would like to make one bee scale, but simple. Is it possible that there are only sensors under the hive or possibly hx711. And when I want to know how much weight it is, I connect only the arduino and it reads the state with hx711. All this interests me because of the consumption of the arduino and the batteries are quickly discharged and the weight is canceled again. I hope you will be able to help me and I am weak with this technique and thank you very much in advance.

@leonardoocchipinti8011 3 года назад

So with HX711 i can only use two strain gauge in a half bridge? Is there a board where i can use four strain gauge in a full bridge?

@murattekin6111 4 года назад

Bro i want to ask a question about hx711 hx711 datasheet says if we send 25 pulse it will send a input if we send it 26 pulse it would answer with b input but there is a huge question in my mind. we have already got the all data before sending 26th pulse.

@fatimafatima-oc7dz 3 года назад

thank you .... please how can i get the software?

@nattawutchaomuang6899 4 года назад

@abdelhafidchafi4194 3 года назад

Hello I used the same organs like you. The problem is, on the screen I get a variation on the value obtained after the weighing. So I need to stabilize this value, I don't know if there is a component / organ (filter for example) that I can use to stabilize the displayed value. Please help me

@harynian 10 месяцев назад

You cant make correct mesurement like that. You have to put things exactly at the center of the platform or you need 4 legs and 4 sensors to compensate the position. Yes, there is something like torque.
