HX711 Module

The HX711 Module is a precision 24-bit analog-to-digital converter (ADC) designed specifically for weighing scales and industrial control applications. It is most commonly used with strain gauge load cells to read weight or force with high accuracy. The module amplifies the tiny electrical signals from the load cell and converts them into digital signals that can be read by microcontrollers like Arduino, Raspberry Pi, ESP32, and others. Its simple 2-wire interface (Clock and Data) makes integration easy for hobbyists and professionals alike. The HX711 is a cost-effective solution for building digital scales, pressure sensors, and smart weighing systems.
