Great Video Sir. I am just wondering if this display is compatible with any type of load cells? Also, if you don't mind, can you link where you got all the components from? Thanks
@@TeardownOZ2CPU Thanks for the quick response Thomas, I appreciate it a lot. Also, regarding the limit of the display, is it possible to change the readings into kilograms instead of grams? I am planning to use it as an experiment using weights ranging from 0-10 kg.
@@nonam3840 YES, like you see in the video, you simply calibrate the readout in the range you want, to the type of sensor you got, if it is 10kg you use as full scale, or 10 grams, or 10 bananas dont really matter
Thomas, good review. Im wondering if I could read the weight data from this module. I am specifically referring to the version with the HX711 chip on it. I also understand that there's the RX/TX pins exposed at the top. Would it be a way to just read in serial what was displayed in the LCD?
@@TeardownOZ2CPU Just got mine, tested it and its pretty impressive but I think I'l still need some time calibrating this properly. However, its rather disappointing not to receive any UART signals from the RX/TX Pins at the top. I suspect it would probably be the STC's Programming port. Have you dig deeper into making this send out the weight via UART? Im not too familiar with the STC 51 series chip set & I believe STC seems to take pride in making sure their programs are safe / extraction proof. Any way to get the source codes for this to be reprogrammed?
Thanks great video....just goes to show information is Key to selecting the right product and is only as good as the info it comes with in this case your video :0)
Glad it was helpful! i was so confused and did not find any info that board i could understand online, so when i finally figured it out, i had the idea to help other people with this video, have a nice day and please come back soon :-)
@@jeffswanson6516 it is possible to connect 4 load cells to one amplifier / readout unint, the schematic is fairly simple, so you dont need 4 units and add the 4 values manually, this is how bathroom scales works, with 4 tiny cells :-)
Hello, does anyone have an idea how in case of loss of contact with a measuring object, on the display the last measured value remains visible, with a button to reset the value and to continue measuring. Thank you so much.
I dont understand the question ? my board got 4 buttons, this video explain how this type of board works, if yours look different, you can most likely not use this video.
@@cungtran2638 i dont think i can explain in text the things i show and tell in the video, so it is faster or more easy to understand, please watch the video a few more times and try to do exactly what i do, if all this fail, please ask a local friend to sit with you and repeat all steps, there is also a tiny chance your board could be defective, or your sensor could be wired up wrong, this will make things not work.
Is the one I was looking for .... if I understand correctly, with this form you don't have to use Arduino and similar stuff for configuration, can everything be done by the module? Just a 5V power supply and a load cell?The max weight bearable weight is almost 10kg (9,999) there are 5-digit modules for greater weights?
YES, all you see, is all you need, NO arduino needed, no software needed, just connect as shown, and 5V the PCB i got, is the one with INTEGRATED HX711, some may have it as a little external pcb, double check this when ordering, not always clear.
@@TeardownOZ2CPU Thank you, I saw this article on Aliexpress while all the other videos I saw spoke of Arduino, this is easier for me ... The only limit is the 4-digit display ... Know similar 5-digit forms to be able to Weigh up to 20-30kg?
@@Demymaker how many kg max, is only defined by the sensor, not the pcb, this one is 5kg max, and with this, the readout goto 999,9 = 0.1gr resolution, and then it continue to 5000 = 1gr resolution, I have not tried a 20 kg sensor, but i bet it will simply continue this way, I would have made the software inside this ic, that way :-)
@@Demymaker i have no clue.. oh, idea.. i could calibrate it, intentionally wrong, and this way fool it, to read out over 9999 grams, I do that in a minute, stay tuned
you can make it measure anything, if you use something that weights in pounds, it when measure in pounds :-) you put in a zero, and a know number for a known weight, could also be used to count eggs :-) put 10 eggs on it, and tell it what ever that weight is = the read out value 10, just one fun example.
@@TeardownOZ2CPU Thank you, I got that part figured out by just playing with it. I am very new to electronics of this type. My Next question/problem is conecting to my computor and showing a bar graph of preasure over a short time.....30 seconds or less
Thank you very much for having synthesized the user manual of this programmable display.
Great video! Managed to get this working with your help!
what's the secret to get the store button to work mine just locks up the system
Why always cannot back to zero after i take the load? Please how to fix this?
If you go into the thousands of grams (or eggs 🤓) does the decimal disappear? Or will it only read out to the hundreds position
Great video, can you please provide links or the name of pics to assemble this device ?
link is in the description, if this dont work for you, go to thingiverse and search for : HX711 scale Display into compleete unit
I connect this to outseal plc via rx tx, are u know what register for this? I try read the data from modbus poll 🙏🙏thx in adv

Hey I know this is an older video but currently trying to make scales with 500kg load cells do you know if this will work?
you can use this board with any type of load cell, 500kg or a mega ton full scale, it is all in the calibration
@@TeardownOZ2CPU thank you very much will have to try it out. Trying to build scales to corner weight a car

for this device, is it possible to export the readings in an excel or any type of file?
plenty of arduino projects released and shared that will interface this one
just google a bit
how to connect the output to the computer
Can you guide me how to calibrate the 3 button display type?
