STEEL ALLOY CONSTRUCTION - Large load cell with a heavy duty steel Hooks are already attached but can be removed. With strain relief wires pre-attached to strain gauges. The device accurately measures forces between 0 and 40 kilograms (0 and 88 pounds).

The HX711, a top-of-the-line load cell amplifier on a breakout board, is designed to provide fast and accurate force measurements, paired perfectly with the load cell. By measuring small changes in resistance of the strain gauges mounted to the load cell, it can directly communicate the results to a microcontroller (such as an Arduino).

A removable hook is pre-attached to the load cell and measures 24 cm) The cables come with wire leads pre-attached in a Five inches) A load cell has a dim of A layer of 8 mm thick, a layer of 7 mm thick.

Questions & Answers

Does this work just as well for compression as it does for ?

In this load cell, tension force is the only force that is measured. It is best to use an aluminum beam style load cell to measure compression.

How precise is the tension load cell and what is its resolution Would Degraw be so kind as to send us the load cell's datasheet?

It depends on the setup which will determine the exact precision. There is an average deviation of Depending on the range of force you intend to measure, accuracy can be as high as 15 Newton. It is possible to set the resolution of decimal numbers any way you like in the Arduino code, but anything beyond 0 will cause errors. A Newton of 01 is unlikely to have any meaning. We are unable to provide a load cell datasheet for this product. By purchasing the load cell from a luggage scale manufacturer who produces the part on-site, we can keep the cost low. Typically, datasheets are not provided since they do not typically offer this house for sale. Please accept my sincere thanks!

It was purchased along with the HX711 and a 40kg load cell. The hx711 key. I can't get Arduino uno to recognize the files I downloaded from gethub as they don't compile. Need assistance?

The Arduino PC software can be accessed by selecting the "Tools" menu, then selecting "Manage libraries". There is an item called ". Then enter "hx711" into the search box and select "HX711 Arduino Library by Bogdan Necula, Andreas Motl", then click "Install" to install the library.

Is there a deflection of the bar when the bar is loaded to its maximum?

Despite being tested under maximum loads, we have not measured the maximum deflection of the bar.

Worked great, but use a 5V microcontroller like the Sparkfun Pro Micro instead

5/5

My goal was to build a digital hanging weight scale (like a fish scale, but for weights) to monitor my dynamic tension between my arms while I'm using a rowing machine. I wanted to do this since I just had rotator cuff surgery. The dual-purpose body is small, light, and has the dual-function already built-in "Thanks to a lot of research online, I found this item to be the perfect choice My rowing machine strap needs to be connected to the hook arrangement. It was difficult for me to get it to work at first, so I contacted Degraw for assistance. Despite the high volume of requests for technical support, Degraw's response time was exceptional. In fact, Mack sent me another unit gratis to see if it was a hardware issue, so I know it might be a hardware issue. This did turn out to be a lot of issues on my end, but as you can see from the plot above, it seems to be fairly linear up to 6Kg (from the tests I conducted). It seems the only problem with the HX711 ADC is that you have to use a 5V supply. The first time I used the 3, I was in a hurry. This revealed marked nonlinearity right at the higher tension ranges, which was caused by the Teensy 3V microcontroller. The issues disappeared as soon as I switched to a Sparkfun Pro Micro 5V.

Contributed appropriate feedback to the project and worked with the Nodemcu team

4/5

It has been said that the wire is very thin by many reviewers. After looping it around and tying it with wire, I was done. In the chicken coop, I use it to weigh chicken feed. Having this on all the time is not a good idea and the weight varies with the I trust it to remind me when to top off the food as I am familiar with when to do so. A MQTT broker on the ESP8266, linked with Home Assistant, brings it all together for me.

The possibility of this working is not guaranteed

3/5

You should be aware of what awaits you as a buyer. My problem is that these products look great on paper, but I'm having an awful time getting them to output anything useful. I've checked the connections, the pinout, and several Arduino libraries and programs to get it to work, but to no avail. The same holds true for calibration as well as Despite getting numbers on the serial monitor, it still says "HX711 not found" even after increasing load cell tension more or less. I saw one reviewer had success in contacting Degraw, but I am not sure how she obtained the contact information for Degraw. I have found it easier to get in touch with sellers on AliExpress using the "message seller" button than I have figuring out how to reach There seems to be a problem with my system If it's my soldering, my pinout connections, the load cell, the HX711, or code for the Arduino. In order for this to work, several factors must be met. I am sure it could be done if others have also been able to solve it. Unfortunately, the evidence I'm seeing does not convince me. At this point, I am not going to recommend this product.

All in all, I'm satisfied with my I was surprised at how small the gauge of the wires is

4/5

It had to be replaced with new wiring just to get the system up and running. While the calibration instructions are a bit poor, it seems to be working now. The trial and error method had a lot of trouble setting it up. The sensor is generally good, but - as is often the case with low-cost sensors like these - I think they are better suited to occasional or tinkering use rather than lifetime wear and tear exposure. The mail had it in a jiffy.

This Arduino tensile tester is designed to test a tensile load

5/5

My old code had another strain cell that used the bending moment of the HX711 board, so it was a breeze to jump in and use this one. The oz found it to be accurate and it worked. Digital fishing scales can be used for fish that weigh between 50 and 60 pounds.

Wires so thin they can be seen

4/5

In a nutshell As a result of the thin wire problem in the reviews, here is my solution. Using headers and a crimper, I made my own ribbon. Ruth my nano will be tested tomorrow, and I will update it accordingly.

There are plenty of fragile wires on cheap sensors, but the sensor works fine - and even below 40 kg it reads with reasonable accuracy

3/5

It's true! As far as I know, you can't really put new wires in if they rip or break. The wires are cheap and very fragile. Do not expect it to last very long. Handle with care.

Thanks to Degraw for the great support! At first, I had difficulty getting a reading from the load cell (my fault entirely), and I contacted Degraw to help

5/5

The man I spoke with was prompt and very helpful when it came to I was sent a replacement load cell with the HX711 board even though it is all my fault.

Hope you'll enjoy shopping with.
