20Kg Load Cell

20Kg Load Cell

β‚Ή95.00Price

πŸ“Œ Overview

The 20Kg Load Cell is a weight/force sensor that measures loads up to 20 kilograms.

πŸ‘‰ It is widely used in:

  • βš–οΈ Digital weighing scales

  • πŸ€– Force measurement systems

  • 🏭 Industrial automation

  • πŸ§ͺ Smart IoT weighing projects

🧠 Working Principle

The load cell works using the concept of Strain Gauge:

  • Inside β†’ metal beam with strain gauges

  • When weight is applied β†’ beam deforms slightly

  • This changes electrical resistance

  • Output β†’ very small voltage signal (mV range)

πŸ‘‰ Requires an amplifier like HX711 to read values

Load Cell β†’ HX711 β†’ Microcontroller

πŸ”„ Working Flow

  • Weight applied

  • Load cell deforms

  • Resistance changes

  • HX711 amplifies signal

  • Microcontroller reads weight

⚠️ Important Notes

  • ⚠️ Cannot connect directly to Arduino (signal too small)

  • ⚠️ Needs calibration for accurate readings

  • ⚠️ Avoid overload beyond 20Kg

  • ⚠️ Must be mounted properly for correct measurement
