Description

The Gyrfalcon HX711-1 module is engineered around the HX711 integrated circuit, providing a complete signal conditioning solution for resistive bridge sensors. It amplifies and digitizes the small differential signals from load cells and strain gauges, converting them into a stable digital output via a simple serial interface. The on-chip low-noise PGA, internal oscillator, and power-on reset circuitry ensure precise, drift-free measurements with minimal external components.

Operating from a wide 2.6V to 5.5V supply, the module is compatible with both 3.3V and 5V logic systems, making it suitable for integration into portable scales, industrial process control, and embedded force-sensing projects. Its dual-channel architecture allows for simultaneous monitoring of two sensors or the use of a tare function.

Frequently Asked Questions

What is the operating voltage range for the HX711-1 module?

The module operates from a wide DC voltage range of 2.6V to 5.5V. This makes it compatible with both 3.3V and 5V microcontroller systems like Arduino, ESP32, and Raspberry Pi without requiring a level shifter.

How do I connect a load cell to the HX711-1 module?

A standard 4-wire load cell connects to the module's screw terminals or pinouts: E+ and E- for excitation voltage (usually from the module), and A+ and A- for the differential signal output. The module provides the regulated bridge excitation and amplifies the resulting millivolt signal.

What is the difference between Channel A and Channel B?

Channel A supports programmable gains of 64 or 128, making it ideal for high-precision measurement of very small signals from primary sensors. Channel B has a fixed gain of 32 and can be used for a secondary sensor or for implementing a tare function with a second load cell.

How do I select the output data rate (10 SPS vs 80 SPS)?

The data rate is selected by controlling the pin state during the power-up sequence or via specific commands in your microcontroller code. The 10 SPS setting offers higher noise rejection for stable readings, while 80 SPS provides faster updates for dynamic measurements.

Does this module require external components to work?

No, the module is a complete signal conditioning solution. It includes an on-chip low-noise PGA, power regulator, and oscillator, requiring no external active components. You only need to connect power, the sensor, and the serial data/clock lines to your microcontroller.
