50kg Human Scale Load Cell Weighing Sensor High Precision Strain Gauge for Arduino in Pakistan

Overview

The 50kg Human Scale Load Cell is an ultra-thin, coin-style resistance strain gauge sensor designed for weight measurement applications. Inside the sensor is a half-bridge strain gauge. When a downward force or weight is applied, the internal metal template bends slightly, altering the resistance of the circuit.

Because the raw voltage output from a single load cell is incredibly small (millivolts), it is typically paired with an external analog-to-digital amplifier like the HX711 module to talk cleanly to an Arduino, ESP32, or Raspberry Pi. This sensor is the standard component choice for engineering students developing smart fitness mats, automated inventory bins, or DIY electronic scales.

Key Features

• Industrial Build Quality: Constructed from rugged alloy steel to withstand continuous physical stress without losing calibration.

• Ultra-Low Profile: Flat, compact design allows it to be easily embedded under platforms, acrylic sheets, or 3D-printed brackets.

• Modular Scalability: Can be used as a standalone sensor with external resistors, or hooked up in a 4-sensor array to create a full Wheatstone bridge capable of reading up to 200kg.

• High Linear Accuracy: Delivers highly repeatable, precise output data across its entire weight range.

Technical Specifications

Wiring Configurations

This is a 3-wire half-bridge sensor. To read it properly, you have three implementation choices:

1. Using One Sensor: Pair it with two external 1k-Ohm resistors to form a full-bridge network for basic weight tracking up to 50kg.

2. Using Two Sensors: Combine two units back-to-back to create a full bridge with a shared capacity of up to 100kg.

3. Using Four Sensors (Recommended): Connect four sensors in a closed loop ring (like a standard bathroom scale) to build a robust full-bridge system that measures up to 200kg.
