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.

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.

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).

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?

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.

Can we a get wrong value when a same weight is placed at different places on the bord ? Because increase in distance between the sensor and the centre of mass of the applied weight can vary the torque. So the resistance of the sensor also vary.

Yes it could. But for this small setup the error is very low. Also if the plate is more solid it will help more. That's why for better results you could use the 4 load cells setup as a body weight scale

The load cells shown with two bolts on either end are contra-flexure differential bending beams. The cut outs cause a near parallelogram movement. These two points reduces by many orders of magnitude the variance based on distance. The non-functional example on a piece of plastic or glass on the end would be proportional to both force and distance. An experience load cell designers job is to negate these effects though combinations of mountings and corrective designs.

Thank you for a very nice video. One question though, how do you expect the longitudinal placement of the load on the load cell to affect the resistance measurement? If you think of it as a bending bar, it seems like the resistance would increase if you place the load further from the strain gauges as the lever arm would be longer.

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.

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.

@kwakeham4 жыл бұрын
The load cells are full wheatstone bridges and therefore passively compensated. A single gage will have high thermal drift characteristics especially if not matched to the material. This matching is matching the thermal expansion of the material to the STC or Self temperature compensation of the gage. This would help, but would not eliminate all of it. It also depends on the material of the element of the gage. Constantan gages have a flatter curve at room temperature, while Karma does not.
