2 Sets 50kg Human Scale Load Cell Weighing Sensor Resistance Strain Half-Bridge Sensor + HX711 A/D Amplifier Weight Module DIY Kit Compatible Arduino

Description

Product Overview

The 2 Sets 50kg Human Scale Load Cell kit from ShangHJ combines precision engineering with user‑friendly design, delivering a versatile solution for weight measurement applications. Each kit includes two half‑bridge strain gauge sensors, each rated for 50 kg, and a high‑performance HX711 A/D converter module. The sensors are constructed from stainless‑steel alloy, offering excellent durability and resistance to corrosion, while the HX711 chip provides 24‑bit resolution for accurate data capture.

Key specifications include:

• Package Dimensions: 4.92 x 4.72 x 0.91 inches
• Weight: 3.53 ounces
• Model Number: S02X8+S19X2
• Operating Temperature: -20 °C to 85 °C
• Output: Millivolt range proportional to load

Designed for seamless integration with Arduino, Raspberry Pi, and other microcontroller platforms, the kit supports multiple wiring configurations. Users can connect a single sensor with an external resistor to form a full‑bridge circuit, pair two sensors for a combined 100 kg capacity, or link four sensors for up to 200 kg. This flexibility makes the kit suitable for a wide range of projects, from hobbyist scale prototypes to laboratory‑grade weighing stations.

Usage

Whether you are building a DIY kitchen scale, a laboratory balance, or a small‑scale industrial weighing system, this load cell kit adapts to your needs. The compact form factor allows installation in confined spaces, while the robust construction ensures long‑term stability under repeated loading cycles. Engineers can employ the kit for prototype development, educators can use it in physics labs to demonstrate force measurement, and makers can integrate it into robotics projects that require precise weight feedback.

Typical use cases include:

• Homebrew or food‑industry scale projects
• Material testing rigs for small components
• Automated inventory weighing stations
• Educational demonstrations of strain‑gauge principles
• Custom balance designs for hobbyist drones and RC models

The kit’s Arduino‑ready interface means you can start coding within minutes using the provided example sketches. Connect the HX711 module to the microcontroller’s digital pins, calibrate with known weights, and retrieve real‑time data for display, logging, or control loops.

FAQ

Can I use the sensors with a microcontroller other than Arduino?

Yes. The HX711 module communicates via a simple two‑wire interface (DT and SCK), which is compatible with most 3.3 V or 5 V microcontrollers, including Raspberry Pi, ESP32, and STM32 boards.

How do I calibrate the load cell for accurate measurements?

Begin by connecting the sensor and HX711 to your microcontroller, then upload the provided calibration sketch. Place a known weight on the sensor, record the raw output, and calculate the scale factor. Update the factor in your code to convert raw values to weight units.

What is the recommended wiring configuration for a 100 kg capacity?

Connect two 50 kg sensors in series to form a full‑bridge circuit, using the external resistor as specified in the manual. This configuration doubles the measurable range while maintaining linearity.

Is there a warranty or return policy?
