7Semi HX711 Load Cell Amplifier Module - 24-bit ADC for Weigh Scales
The 7Semi HX711 is a precision 24-bit analog-to-digital converter (ADC) and load cell amplifier module, designed to interface directly with strain gauge bridge sensors. It provides a high-resolution digital output for accurate weight measurement, compatible with microcontroller platforms like Arduino, Raspberry Pi, and ESP32.
Features
- 24-bit Σ-Δ ADC for high-resolution weight measurement.
- Dual differential input channels (A & B) with programmable gain (32, 64, 128).
- Wide operating voltage range (2.6V to 5.5V) suitable for battery-powered and embedded systems.
- Selectable data output rates of 10 SPS (for low noise) or 80 SPS (for faster response).
- Integrated low-noise PGA and on-chip power supply regulator simplifies circuit design.

The HX711 is a dedicated weigh-scale ADC that converts the small differential signal from a load cell or strain gauge bridge into a stable 24-bit digital output. Its integrated programmable gain amplifier (PGA) and power regulator eliminate the need for external signal conditioning components, providing a robust and simplified interface for precision measurement systems.
Engineered for stability, the module features excellent common-mode and power supply rejection (100 dB each), minimizing errors from electrical noise. Its low power consumption and flexible clocking options (internal or external) make it ideal for portable scales, industrial process control, and automation applications requiring reliable force or weight sensing.
