Load Cell 5kg including HX711 Amplifier

Product Overview

The 5kg Straight Bar Load Cell bundled with the HX711 ADC Amplifier Module provides a complete precision force-measurement solution for microcontrollers such as Arduino, ESP32, and Raspberry Pi. The load cell utilizes a robust aluminum alloy strain gauge transducer capable of measuring forces up to 5 kilograms with high accuracy. The included HX711 breakout board features a specialized 24-bit high-precision analog-to-digital converter designed specifically for weigh scales and industrial process control applications.

Technical Specifications

The load cell features an alloy steel and aluminum construction with M4 and M5 mounting holes for easy mechanical installation. Operating with a non-linearity rating of less than 0.05 percent full scale, it delivers exceptional repeatability and low hysteresis. The HX711 amplifier chip incorporates an integrated low-noise programmable gain amplifier with selectable gain options of 32, 64, or 128. Operating across a supply voltage range of 2.6V to 5.5V, the module integrates an on-chip power supply regulator for load-cell and ADC analog power supplies, eliminating the need for external regulating circuitry.

Wiring and Signal Integration

Connecting the load cell to the HX711 board requires standard four-wire color coding: Red for Excitation positive (E+), Black for Excitation negative (E-), White for Output negative (A-), and Green for Output positive (A+). The digital interface communicates via a simple two-wire serial connection (Data and Clock) that connects directly to standard microcontroller GPIO pins, simplifying firmware development using widely available open-source libraries.

Target Applications

This sensor combo is ideal for digital kitchen scales, industrial automation feedback systems, filament remaining monitors in 3D printers, inventory tracking bins, dynamic force sensing experiments, and custom robotics payload measurements.
