uxcell 100kg 42mmx38mmx3mm Electronic Scale Body Load Cell Weighing Sensor for Kitchen Scale,Human Body Bathroom Scale, Jewelry Scale

This product works quite well and produces repeatable results. For those wondering about the wiring, It's rather easy and somewhat obvious, my first guess was correct:Red = Excitation +Black = Excitation -White = Amplifier+, Signal+ or Output+Green = Amplifier-, Signal- or Output-The white and green wires should be interchangeable considering that most load cell amplifiers operate using a differential amplifier.Once you get the load cell working properly you will simply have to calibrate it with a known weight.I' m using this product with along with the follow load cell conversion module:DIYmall 2pcs Hx711 Weight Weighing Load Cell Conversion Module Sensors Ad Module for Arduino Microcontrollerhttps://www.amazon.com/gp/product/B010FG9RXO/ref=oh_aui_search_asin_title?ie=UTF8&psc=1

I bought this because they are unique insofar that they are rated at up to 100kg instead of just 50kg.Shipping was fast and reasonably priced!Unfortunately this load cell does not come with the clamp on top, which you should use to get accurate readings.So I had to improvise one from parts from the hardware store.Moreover there is very little documentation. Which color cables are excitation+, excitation-, signal(a)+, and signal(a)- ?Also the four load cells I bought don't have the same cables. So you don't have the same colors from one piece to the next.I contacted the seller about this, but I have not gotten an answer in a month.Now I brute forced the cables and got some reading. I tested it with 5kg and 10kg so far and it worked.Still the sparse documentation and the poor support leaves me not liking this product.I hope this review is useful to you.
