HX711 Load cell / Strain Gauge Calibration and Weight Measurement using Arduino

[@DaPutz]

Needed for fix some lines like I found them in other hx711-code:
HX711 scale;
...
void setup() {
scale.begin(DOUT, CLK);
Works! Thanks! Calibration factor also works for my device here (5 KG)

[@zafir3674]

Sir can u copy me code that ur using bcz mine cant work

[@krisk3035]

Thank you for showing and practically explaining Calibration factor

[@TheEdmaster87]

Hi. Is the load cell good enough to measure a scew or a bolt tension which has been tighted with a nut and washer? To see if it becomes loose over time?

[@mahtamajidi9680]

Hi. Can I use two strain gauges mounted on a frame to replace the loadcell?

[@harshav811]

Is calibration required when ever i turn it on ?

[@brianchivatsi1771]

How should I contact you for a similar project?

[@parthkale6862]

Best tutorial

[@ElectroniClinic]

thanks bro

[@kaushikkumar3639]

Thank you brother

[@syaz_9763]

sir, can you share that coding ? i use load cell 50kg but it keep give me reading even without touch my load cell and that value is too big

[@Arachisage]

When i do not place any load on my load cell, the readings keep changing from -0.5kg to 2kg. My load cell is rated up 5kg. What could be wrong ?

[@ElectroniClinic]

calibrate

[@Arachisage]

@@ElectroniClinic Yup i have gone through the callibration steps. The reading starts from 0, but beings to gradually creep upwards. Sometimes it gives strange readings like 30kg.

[@nagaprivieen7343]

Can i use this to measure pulling force of a wire?

[@ElectroniClinic]

yes you can use this, but for this you will have to design some mechanical structure. and you will need to calibrate this. the calibration part i have already explained.

Superb Video👍👍

[@Mari-ih4iv]

HX711 on line 4 code is changing into color red. And arduino calls out it as an error, what should we do? Thankyou

[@TheFlipDeucheBack]

hi how to change to gram? what is the calibration

[@brilitech]

i have only 3 wire load cell so how to connect with hx711 module ?

[@flawns]

how about a strain gauge? For my application, I do not have room to attach a block of metal.

[@ElectroniClinic]

tell me in detail. for what purpose you want to use it?

[@flawns]

@@ElectroniClinic It will be underneath my car! It is a sway bars to be exact. I want to take data from the stock sway bar and then repeat it again for the aftermarket one.

[@jeffreyespiritu9232]

HI, can I use the same code for the 200kg weight sensor?

[@ElectroniClinic]

Yes. You will only need to change the calibration value. And most importantly use a load cell which is designed for 200kg or more

[@jeffreyespiritu9232]

@@ElectroniClinic what calibration will i put in the code..sorry sir im just new to arduino..

[@ElectroniClinic]

its just through hit and trail... watch this video completely. i have explained this method.

[@mariaalpis5776]

hi, what was the calibration factor that worked for you for the 200kg weight sensor?
thank u

[@اختراعاتوابتكارات-ج3ع]

I want an amendment to the HX711 code so that when I get to a weight of 1 kg, the LED works on port number 13

[@afaqkhan3348]

. Amazing

[@chung_myung.]

Sir what do +B and -B pins do?

[@Edu_Pi]

Cathode and Anode

[@AkoSeaMark]

Any calib factor for grams

[@ElectroniClinic]

you have to check this yourself. select a value which works best for you.

[@pvravi478]

Anyone can say 150 kg load cell calibration factor

[@soutikbera167]

can u share the code?

[@ElectroniClinic]

code is available on website, check link in the description.

[@soutikbera167]

@@ElectroniClinic thank u so much

[@mguarin912]

Your title read strain gauges. All you showed were load cells. Come on man.
