Arduino Weight Sensor 10kg | DIY Smart Weighing Projects

Build Accurate 10kg Weight Measurement Systems with Arduino

Whether you’re creating a DIY digital scale, smart feeder, or industrial prototype, an Arduino weight sensor 10kg setup is ideal for precise measurement. Load cells combined with an Arduino allow you to measure weights up to 10 kilograms with high accuracy, logging data, triggering events, or automating devices.

What is an Arduino Weight Sensor 10kg?

An Arduino weight sensor 10kg project uses:

  • Load Cell (10kg capacity) – Converts weight into electrical signals.

  • HX711 Amplifier – Converts millivolt output from the load cell into readable digital data.

  • Arduino Microcontroller – Processes and interprets the weight data.

Applications:

  • Smart pet feeders and food dispensers

  • Mini bars and inventory tracking

  • DIY scales for home or lab

  • Industrial automation and process monitoring

How to Connect a 10kg Load Cell to Arduino

Components Needed:

  • 10kg load cell

  • HX711 amplifier module

  • Arduino Uno / Nano / Mega

  • Jumper wires

  • Optional: 3D-printed housing or platform

Wiring Setup:

  1. Connect load cell wires to HX711:

    • Red → E+

    • Black → E-

    • White → A-

    • Green → A+

  2. Connect HX711 to Arduino:

    • DOUT → Arduino digital pin 3

    • SCK → Arduino digital pin 2

    • VCC → 5V

    • GND → GND

Arduino Weight Sensor 10kg Code


#include "HX711.h" #define DOUT 3 #define CLK 2 HX711 scale; void setup() { Serial.begin(9600); scale.begin(DOUT, CLK); scale.set_scale(2280.f); // Adjust based on calibration scale.tare(); // Reset scale to 0 } void loop() { float weight = scale.get_units(10); // Average of 10 readings Serial.print("Weight: "); Serial.print(weight, 2); Serial.println(" g"); delay(500); }

Tips:

  • Adjust scale.set_scale() after calibration with a known weight.

  • scale.tare() ensures the scale starts at zero before weighing.

Calibrating Your 10kg Weight Sensor

  1. Place a known weight on the sensor (e.g., 1kg, 5kg).

  2. Record the raw reading.

  3. Adjust set_scale() in code until the reading matches the known weight.

  4. Test multiple weights to ensure linear accuracy up to 10kg.

Applications of Arduino Weight Sensor 10kg

  • Smart Cat/Dog Feeders – Automate daily food portions.

  • Mini Bars – Detect and record item removal.

  • DIY Scales – Kitchen, lab, or small industrial scales.

  • Industrial Monitoring – Track bin or tank weights for inventory.

  • IoT Projects – Connect to cloud dashboards for analytics and alerts.
