The HX711 ADC Load Cell Amplifier Module – Purple is a high-precision 24-bit analog-to-digital converter specially designed for load cell and weighing applications. It features an integrated amplifier that enables microcontrollers to detect extremely small resistance changes from Wheatstone Bridge-based load cells. Because of its high resolution and stable amplification, it is ideal for digital weighing scales, force sensing systems, and industrial measurement devices.
This module supports two input channels with programmable gain options of 128x for Channel A and 64x for Channel B. Therefore, it allows flexible configuration depending on sensitivity and measurement requirements. The HX711 communicates using a simple two-wire digital interface (Clock and Data), making it easy to integrate with Arduino, STM32, ESP32, and other microcontroller platforms.
With low power consumption and compact 22mm × 22mm size, this module is perfect for embedded, portable, and IoT-based weighing solutions. If your project requires accurate and reliable weight or force measurement, the HX711 module provides a dependable and cost-effective solution. Featured By RoboticsBD.
