Perfect for Arduino enthusiasts and professionals building custom body scales or industrial weight sensors, it combines durable materials with advanced electronics to deliver accurate, reliable measurements. ## Description Product description 50kg Load Cell This load sensor, sometimes called a strain gauge, is the same one found in digital bathroom scales (you know, the ones you use in January for your New Year’s resolutions, and then forget about a month later). The sensor is a group of half-bridge strain gauge, there are 3 ways to use it 1. Use one sensor with an external resistor to form a full-bridge measurement, the range of a sensor range: 50kg. External resistance on the higher requirements. 2.Use two sensors to form a full-bridge measurement, measuring range for the sum of the two sensors: 50kgx2 = 100kg 3.Use four sensors to form a full-bridge measurement, measuring range for the sum of four sensors: 50kgx4 = 200kg HX711 AD Module This module uses 24 high precision A/D converter chip hx711. It is a specially designed for the high precision electronic scale designwith two analog input channelthe internal integration of 128 times the programmable gain amplifier. The input circuit can be configured to provide a bridge type pressure bridge (such as pressureweighing sensor mode)is of high precisionlow cost is an ideal sampling front-end module. Features Operation supply voltage range: 2.6 - 5.5V Operating Temperature Range:-20 degree ~ +85 degree Simple digital control and serial interface: pin-driven controlsno programming needed Selectable 10SPS or 80SPS output data rate Simultaneous 50 and 60Hz supply rejection Current consumption including on-chip analog power supply regulator: normal operation < 1.5mApower down < 1uA Two selectable differential input channels On-chip active low noise PGA with selectable gain of 3264 and 128 On-chip power supply regulator for load-cell and ADC analog power supply On-chip oscillator requiring no external component with optional external crystal On-chip power-on-reset About US ——Professional service, Integrity operation, Customer first. ——We have always cared about the customer experience and improve the product function details. ——We will be responsible for any damages or losses incurred in the shipping process. Review: Works as advertized - 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. 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 | #288,443 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #31 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 67 Reviews | | Item Weight | 80 Grams | | 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.

Got tired of over filling the chip barrel and clogging the filters. Not complete yet but making progress. ## Frequently Bought Together - Geekstory 4pcs 50kg Load Cell Half Bridge Strain Gauge Human Body Scale Digital Weighting Sensor + 1pc HX711 AD Amplifier Weight Module for Arduino - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - Arduino Uno REV3 [A000066] --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/70091936-4-pcs-50kg-load-weighting-sensor-amplifier-1pcs-hx711-ad](https://www.desertcart.sn/products/70091936-4-pcs-50kg-load-weighting-sensor-amplifier-1pcs-hx711-ad) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-05-30*
