Operating between 2.7V and 5V with under 1.5mA current consumption, it offers selectable data rates of 10 or 80 samples per second and robust 50/60Hz noise rejection. Perfect for DIY industrial scales, process control, and presence detection, it integrates seamlessly with any microcontroller via a simple two-wire interface supported by numerous libraries. ## Description The Load Cell Amplifier is a small breakout board for the HX711 IC that allows you to easily read load cells to measure weight. By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell and with some calibration you’ll be able to get very accurate weight measurements. This can be handy for creating your own industrial scale, process control, or simple presence detection. The HX711 uses a two wire interface (Clock and Data) for communication. Any microcontroller’s GPIO pins should work and numerous libraries have been written making it easy to read data from the HX711. Check the hookup guide below for more information. Load cells use a four wire wheatstone bridge to connect to the HX711. These are commonly coloured RED, BLK, WHT, GRN, and YLW. Each colour corresponds to the conventional colour coding of load cells: Red: (Excitation+ or VCC) Black: (Excitation- or GND) White: (Amplifier+, Signal+, or Output+) Green: (A-, S-, or O-) Yellow : (Shield) The YLW pin acts as an optional input that is not hooked up to the strain gauge but is utilized to ground and shield against outside EMI (electromagnetic interference). Please keep in mind that some load cells might have slight variations in colour coding. ## Features - Operation Voltage: 2.7V-5V, Operation Current: < 1.5mA - Selectable 10SPS or 80SPS output data rate - Simultaneous 50 and 60Hz supply rejection - Model number: SEN-13879 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00NPZ4CPG | | Best Sellers Rank | #158,778 in Electronics ( See Top 100 in Electronics ) #987 in Audio Component Amplifiers | | Brand Name | SparkFun | | Customer Reviews | 4.0 4.0 out of 5 stars (29) | | Global Trade Identification Number | 06955900326450 | | Item Dimensions | 1.18 x 0.91 x 0.2 inches | | Item Weight | 0.01 Kilograms | | Manufacturer | Cool Components | | Maximum Supply Voltage | 5 Volts | | Minimum Supply Voltage | 2.7 Volts | | Model | SEN-13879 | | Mounting Type | Surface Mount | | Part Number | SEN-13879 | | Specification Met | Nist | | UPC | 717520030058 602401874688 | | Unit Count | 1.0 Count | | Voltage | 5 Volts | ## Product Details - **Item dimensions L x W x H:** 1.18 x 0.91 x 0.2 inches - **Manufacturer:** Cool Components - **Maximum Supply Voltage:** 5 Volts - **Minimum Supply Voltage:** 2.7 Volts - **Voltage:** 5 Volts ## Images ![SparkFun Load Cell Amplifier - HX711 - Image 1](https://m.media-amazon.com/images/I/61VizkyZc-S.jpg) ![SparkFun Load Cell Amplifier - HX711 - Image 2](https://m.media-amazon.com/images/I/51KoQUxT02L.jpg) ![SparkFun Load Cell Amplifier - HX711 - Image 3](https://m.media-amazon.com/images/I/51OP2Xo4DFL.jpg) ![SparkFun Load Cell Amplifier - HX711 - Image 4](https://m.media-amazon.com/images/I/51Y91cw2MML.jpg) ## Frequently Bought Together - SparkFun Load Cell Amplifier - HX711 - Arduino UNO R4 WiFi [ABX00087] – Renesas RA4M1 + ESP32-S3, Wi-Fi, Bluetooth, USB-C, CAN, 12-bit DAC, OP AMP, Qwiic Connector, 12x8 LED Matrix for Advanced IoT & Embedded Projects - 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 --- ## 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.es/products/11062923-sparkfun-load-cell-amplifier-hx711](https://www.desertcart.es/products/11062923-sparkfun-load-cell-amplifier-hx711) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-07-08*
