Why Use a Weight Sensor with Arduino?

Weight sensors (commonly load cells) measure force or weight and convert it into an electrical signal. Arduino boards, with their easy-to-use analog/digital input pins and libraries, can process this data and make it actionable.

✅ DIY Scales – Kitchen, jewelry, or lab scales
✅ Smart Farming – Monitor feed, soil, or crop weight
✅ IoT Devices – Send weight data to the cloud
✅ Automation Systems – Control filling machines or conveyors
✅ Robotics – Measure gripping force in robotic arms

Components You Need

To set up a weight sensor compatible with Arduino, you typically need:

• Weight Sensor / Load Cell (1kg, 5kg, 10kg, 50kg, or higher capacity)

• HX711 Amplifier Module – Converts small mV signals into Arduino-readable data

• Arduino Board (Uno, Nano, Mega, etc.)

• Wires & Breadboard – For connections

• Arduino HX711 Library – For coding and calibration

How to Connect a Weight Sensor to Arduino

1. Wire Load Cell to HX711

   • E+ → Red wire

   • E- → Black wire

   • A+ → White wire

   • A- → Green wire

2. Connect HX711 to Arduino

   • DT → Digital Pin 2 (example)

   • SCK → Digital Pin 3

   • VCC → 5V

   • GND → GND

3. Upload Arduino Code

   • Install HX711 Arduino library

   • Calibrate with known weights

   • Start reading and printing weight data via Serial Monitor
