DFRobot Gravity Digital Weight Sensor Kit - HX711 Load Cell Amplifier Module
The DFRobot Gravity Digital Weight Sensor is a precision measurement kit based on the HX711 24-bit ADC, designed for interfacing directly with strain gauge load cells. It provides a simple digital interface compatible with Arduino, Raspberry Pi, and other 3.3V/5V microcontrollers for accurate weight and force sensing applications.
Features
- High-precision 24-bit analog-to-digital converter (HX711) for accurate weight measurement.
- Gravity 3-pin interface for plug-and-play compatibility with DFRobot shields and standard microcontrollers.
- On-chip programmable gain amplifier (PGA) with selectable gains of 32, 64, and 128.
- Dual differential input channels for flexible load cell connection.
- Integrated power supply regulator for stable sensor excitation and ADC operation.

This sensor module utilizes the HX711, a dedicated weight scale converter that interfaces directly with a Wheatstone bridge sensor (load cell). It converts the millivolt-level analog signal from the strain gauge into a high-resolution digital output, significantly improving measurement reliability and noise immunity compared to basic ADC solutions.
The module features an on-chip low-noise PGA and power regulator, simplifying system design by providing a stable excitation voltage for the load cell. Its simple serial interface requires only two digital I/O pins for data and clock, making it easy to integrate into Arduino, ESP32, or industrial control projects requiring precise force or weight monitoring.
