Happy so far Review: It works as expected - The instructions provided work and I am able to get close to accurate measurements without much effort. The one issue I had to figure out is how the metal must be mounted. If it is mounted even slightly incorrectly it will give odd and bogus data. The key is to have the outer perimeter lifted off of the mounting surface enough that the center metal hangs freely. It was only about 2mm but it made all of the difference. I'm only giving it 4 stars because the wires are very thin and seem quite breakable. ## Features - This load sensor, sometimes called a strain gauge, is the same one found in digital bathroom scales - The sensor is a group of half-bridge strain gauge, there are 3 ways to use it - This module uses 24 high precision A/D converter chip hx711, specially designed for the high precision electronic scale - You will receive 4pcs 50kg Half-bridge Load Cell + 1pc HX711 AD Weight Module - If you need technical documentation, please click “Geekstory‘’to em-ail us ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B079FTXR7Y | | Best Sellers Rank | #139,501 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #18 in Industrial Scale & Balance Parts | | Blade Material | Stainless Steel | | Blade Material Type | Stainless Steel | | Brand | Geekstory | | Brand Name | Geekstory | | Color | Green & Silver | | Customer Reviews | 4.1 out of 5 stars 68 Reviews | | Item Weight | 80 g | | Manufacturer | Geekstory | | Manufacturer Part Number | 1 | | Material | Polycarbonate | | Material Type | Polycarbonate | | Model Number | FZ1802AX4+FZ0728 | | Number of Items | 4 | | Operation Mode | Manual | | Size | Small | | UPC | 702795764395 | ## Product Details - **Blade Material:** Stainless Steel - **Brand:** Geekstory - **Color:** Green & Silver - **Material:** Polycarbonate - **Size:** Small ## Images ![4 PCS 50kg Load Weighting Sensor Amplifier+ 1pcs HX711 AD Weight Module - Image 1](https://m.media-amazon.com/images/I/71aasrdT0oL.jpg) ![4 PCS 50kg Load Weighting Sensor Amplifier+ 1pcs HX711 AD Weight Module - Image 2](https://m.media-amazon.com/images/I/61OAt6QaWBL.jpg) ![4 PCS 50kg Load Weighting Sensor Amplifier+ 1pcs HX711 AD Weight Module - Image 3](https://m.media-amazon.com/images/I/61mavqXA3cL.jpg) ![4 PCS 50kg Load Weighting Sensor Amplifier+ 1pcs HX711 AD Weight Module - Image 4](https://m.media-amazon.com/images/I/71fzVQwH7OL.jpg) ![4 PCS 50kg Load Weighting Sensor Amplifier+ 1pcs HX711 AD Weight Module - Image 5](https://m.media-amazon.com/images/I/510IHq5HSHL.jpg) ## Questions & Answers **Q: How accurate can I measure items? If I use more than one cell does the accuracy improve or degrade?** A: This type of cell, which is 50kg half bridge will provide a typical accuracy of 50 to 100g with a maximum range of 200K for 4 cells. Adding more cells will increase the maximum load and decrease accuracy. **Q: What is the output format from the hx711 ad weight module? is this an i2c output? if so what's the address?** A: The output is not IIC, it is SPI **Q: Is there a way to get the 80 hz sample rate that the hx711 should provide (according to the datasheet) if the rate pin is set to high?** A: You need cut the PIN 14 of the chip to get 80 HZ **Q: I just bought these for a project. What two opposing points get pressure applied to measure strain? I suspect it needs the rivets to be clear?** A: This gauge is used for scales, gauge must rest on it outer ring and the pressure must be applied on the center point. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as advertized *by E***E on September 7, 2022* It took a while to find the proper circuitry needed to use, but once i did i was able to hook these up and they seem to work well.
