HX711 Weighing Pressure Sensor Module Big Size with Soldering

The HX711 Module is a compact breakout board featuring the HX711 IC, designed to interface with load cells and provide precise 24-bit weight measurements. It connects to your microcontroller via a simple two-wire interface (Clock and Data), allowing for easy calibration of the load cell to ensure accurate readings. This module is ideal for applications such as industrial scales, process control, or presence detection. Numerous libraries are available, making it easy to integrate the HX711 with various microcontrollers.

Load cells typically consist of four wires arranged in a Wheatstone bridge configuration, which are connected to the HX711. These wires are commonly color-coded as RED, BLK, WHT, GRN, and YLW.

Each colour corresponds to the conventional colour coding of load cells :

1. Red (Excitation+ or VCC).
2. Black (Excitation- or GND).
3. White (Amplifier+, Signal+, or Output+).
4. Green (A-, S-, or O-).
5. Yellow (Shield).

The YLW pin acts as an optional input that not hook up to the strain gauge; but is utilized to ground and shield against outside EMI (electromagnetic interference). Please keep in mind that some load cells might have variations in colour-coding.

Frequently Asked Questions

What types of load cells can I use with this HX711 module?

This module supports standard 4-wire Wheatstone bridge load cells (RED, BLK, WHT, GRN). It works with most strain gauge load cells rated up to the module’s input range, making it suitable for both low-capacity and high-capacity scales.

How do I calibrate the HX711 Weighing Pressure Sensor Module?

After wiring, upload an HX711 library example to your microcontroller and place a known test weight on the load cell. Note the raw ADC output and compute the scale factor by dividing the difference in reading by the known weight. Enter this factor into your code to translate raw readings into weight units.

What voltage supply does the HX711 module require?

The HX711 operates from a single supply between 2.6 V and 5.5 V. For most microcontroller projects, we recommend using a stable 5 V supply to ensure full PGA performance and noise immunity.
