Description

This sensor kit combines a robust aluminum alloy load cell with the industry-standard HX711 analog-to-digital converter. The load cell operates on the strain gauge principle, where applied force causes a proportional change in electrical resistance, which is then converted into a high-resolution digital signal by the HX711 chip. The module provides a straightforward serial interface for reading data via microcontrollers.

Designed for prototyping and educational use, the kit offers a complete solution for converting mechanical force into a digital signal. The HX711 module’s integrated PGA and 24-bit delta-sigma ADC ensure stable and accurate readings, making it suitable for applications requiring precise weight or force monitoring in a compact form factor.

Key Features

  • High-precision 5kg load cell constructed from durable aluminum alloy.
  • HX711 module features a 24-bit delta-sigma A/D converter for exceptional resolution.

Frequently Asked Questions

What is the operating voltage range for the HX711 module in this kit?

The HX711 module operates from 2.6V to 5.5V DC. This wide range makes it compatible with both 3.3V and 5V logic systems, such as Arduino Uno (5V) or ESP32 (3.3V). Ensure your microcontroller's I/O pins are compatible with the module's logic level.

How do I wire the load cell and HX711 module to my Arduino?

Connect the load cell's four wires (typically Red, Black, White, Green) to the HX711 module's designated E+, E-, A+, A- terminals. Then, connect the module's VCC, GND, DT (Data), and SCK (Clock) pins to corresponding 5V, GND, and digital pins on your Arduino. Use the HX711 library for straightforward data reading.

Does the kit require calibration before use?

Yes, calibration is required for accurate measurements. You must establish a calibration factor by placing a known weight on the load cell and using the HX711 library's calibration function. The process is documented in most Arduino HX711 library examples and is essential for converting raw ADC counts to weight units.

What is the purpose of the selectable gain on the HX711?

The HX711's programmable gain amplifier (PGA) allows you to amplify the small signal from the load cell. Gains of 32, 64, or 128 can be selected via software to optimize the input signal range for your specific load cell's output, improving measurement resolution and signal-to-noise ratio for different applications.
