Load Cell Kit Build

[@kasmonal4020]

Can we connect two independent loadcells to the hx711 card?

[@TheDradge]

Good video. Wouldn't you need some metal plates to contact the load cells so the pointy bits don't dig into the plywood?

[@FPChris]

How can I use just one of these type cells and get it to read when pressed and released?

[@jjlarrea]

So are we going to see the platform installed in the coop? I am very curious whether by looking at delta weight values you can tell whether a chicken comes on or off the platform, deposits an egg (or one is removed), adds to the 💩 load etc. and maintain an accurate inventory over time. Or is the signal just too noise-ridden for that?

[@ikhrampr611]

what generation of hx711 library are you using sir?

[@associaizioneapecarnicafri9852]

Beautiful but where can I buy those plastic supports for the load cells?

[@MrTidangerous]

I 3d printed them. The link is in the description for the stl file. If you don't have a 3d printer u may be able to order them through thingiverse.

Zero experience in Arduino here -- I have found a few kits on Amazon but don't know which one to buy for this project, any suggestions? Also, is the scale built this way works 100% accurately?

[@michaelzhao58]

What library did you use?

[@tamarajovanovic9820]

Can you please share the example and library you used?

[@dafatra13]

what is the maximum weight that can be detected by 4 load cell(50kg)?

[@andrejvujic]

Great video… What cables did you use to connect the Hx711 with the mini computer?

[@ikhrampr611]

I use the latest Arduino, can you share the code you use in the video?

[@gritnix]

I'd like to mention that when I tried to us similar load cells with a persistent load, they creeped terribly over time. They never really stopped creeping, so it was exceptionally difficult to use them. These cells are made for a scale that has load that's applied and then removed like a shipping scale. I'd like to hear about your experience with trying to use them with a persistent load because I just gave up after seeing the creep.

[@AztecWarrior69_69]

What are you talking about creep?

[@aldosenn]

Hi Gritnix!!. I'm in the same challenge as yours, could you find a system of cells that resist constant weight? I need to weigh drinks. Thanks so much!!

[@gritnix]

@@aldosenn worth mentioning that what's in this video are load sensors, not sure if he says that or not. The sensor is 1/4 of a wheatstone bridge, put 4 together and you have the whole bridge. A real load cell is the whole bridge in one cell. It will still creep but will stabilize over time. It will be rated as having a certain amount of creep over the course of 30 minutes, usually in the range of some tenths of a percent of the total weight. A parallel beam load cell or a compression load cell is what you want. It's really a case of you get what you pay for, and if you're really concerned about the creep, don't buy anything that doesn't tell you what the creep is. The more accurate you want to be, the more money you'll spend. Also, the HX711 used here is not a very robust chip in terms of temperature. I've read where someone said they could essentially use it as a thermometer. If your scale will be in a fairly tight temperature range, no big deal, it'll be fine. But if you'll have big swings, not fast swings, but just large, then you'll want something better.

How can i check if the cell is not working

[@ugursen9020]

firstly thank you for this nice video and i have a question for you, what if we need to measure weight in sloping base, how to combine the sensor data which would be different from each sensor?

[@rodrigoleandro5962]

What material is this support made of? Can the type of material interfere with the readings?

[@baucez]

I did the same thing but the signal was very noisy. The measure was oscillating between +-5kg and it was also influenced by people moving around it (without touching it).

[@AntiRobotCommittee]

the load cells only work for 50kg so i doubt it was +- 5kg. also you can change the gain. search for load cell gain i think its 32 , 64, or 128 idk im just remembering

[@baucez]

@@AntiRobotCommittee I fixed it by rewiring the circuit. The very high noise was probably caused by a faulty connection

[@GaryMcKinnonUFO]

Nice job. What kind of Arduino is that, i've not seen one like it before ? Thanks for sharing :)

[@msqru]

Hi. if the sensor is under load all the time, will it affect its performance? Will it stop working due to deformation?

[@giovannifabris2530]

it will probably drift but settle over time...could plot the function of it and write in your code to compesate. If the platform you are placing them on deforms, yes you will get messed up measurements.

[@stickystick6969]

hello sir! do u have any wiring sample for single piece load cell? or this loadcell needed to be 4pcs per HK711?

[@royerzurumluoglu2466]

A bit late but here you go: instructables.com/id/Arduino-Bathroom-Scale-With-50-Kg-Load-Cells-and-H/

[@GURU_85]

Thanks for Sharing the Info..I have made similar arrangements Circuit But My Hx711 not Giving Constant reading And Not Responding to calibration. Giving Random Readings during calibration .. Please help

[@yellamaidecastro1061]

Did you're problem solve?

[@ardigunawan6552]

can I request the program with the series picture?

[@AztecWarrior69_69]

Would you send please make and send me 3 - 5 sets of those Human Scale Load Cell holders? I can pay with paypal. Also do you have the link to the HX711 AD library you used? Thank you very much for the great video.

[@muzisyenmuhendis]

thx

[@s.u.6198]

but that is not eve close to what this sensor can do !

[@vincentdesaulniersbroussea8639]

hello, if you are talking about a bar type load cell you can see it here : www.instructables.com/id/How-to-Interface-HX711-Balance-Module-With-Load-Ce/ However I don't think HX711 is the right amplifier if you are looking at a half-wheatstone bridge or quarter bridge configuration (which is using only 1 or 2 of the 4 load cells in the video)
