HX711 Load Cell Amplifier Module – High-Precision 24-Bit ADC Weight Sensor for Accurate Weighing, 10Hz Output Rate, PCB Integration
The HX711 Module is a compact, high-precision 24-bit analog-to-digital converter (ADC) specifically designed for weighing applications using strain gauge-based load cells. This module acts as an amplifier and signal processor, accurately converting small changes in voltage from a load cell into digital data that can be interpreted by microcontrollers such as Arduino, ESP32, STM32, Raspberry Pi, and others.
Capable of sampling at 10Hz (standard mode), the HX711 ensures stable and accurate weight readings ideal for electronic scales, pressure sensing, and other precision measurement projects. Its two differential input channels and built-in programmable gain amplifier (PGA) make it easy to interface with various load cells while minimizing the need for additional circuitry.
The module is perfect for integration onto a PCB (printed circuit board) in embedded systems and compact devices where accuracy, low power consumption, and minimal component count are essential.
