HX711 Weighing Dual-Channel 24-Bit Precision A/D Pressure Sensor Module

The HX711 Load Cell Amplifier Module is a high-precision 24-bit analog-to-digital converter designed specifically for electronic weighing systems and load cell applications. It integrates the HX711 IC with a built-in programmable gain amplifier (PGA), enabling accurate measurement of very small signals from strain gauge load cells.

This module features dual-channel differential inputs and supports selectable gain levels of 32, 64, and 128, making it ideal for precision weight measurement and force sensing. With a simple 2-wire serial interface (DT and SCK), it can easily interface with microcontrollers such as Arduino, ESP32, Raspberry Pi, and other embedded platforms.
