HX711 24Bit Precision ADC Module

The HX711 24-Bit Precision ADC Module is a professional-grade analog-to-digital converter module specifically designed for high-precision weighing and pressure measurement applications. Built around the HX711 ADC chip, the module integrates a low-noise programmable gain amplifier (PGA) and provides highly accurate digital conversion for load cells and bridge sensors.

The module supports two selectable differential input channels, enabling flexible sensor interfacing for electronic scales and pressure sensing systems. Its integrated PGA supports selectable gains of 32, 64, and 128, allowing accurate amplification of very small analog signals from load cells.

Designed for low power consumption and reliable performance, the HX711 module includes an internal regulator, oscillator, power-on-reset function, and excellent rejection of 50Hz and 60Hz power supply noise. It is widely used with Arduino, ESP32, Raspberry Pi, and other microcontroller platforms for precision measurement applications.
