Load Cell Sensor

A Load Cell is a sensor that measures the force or weight applied to it. They are commonly used in weighing scales, industrial machines, and other applications where weight measurement is needed. The sensor works by converting the force or weight into an electrical signal which can be processed by a microcontroller.

Applications:

• Weighing scales
• Force measurement in industrial applications
• Load monitoring systems
• Pressure sensors in machinery

Key Features:

• Highly accurate force/weight measurements
• Wide range of applications (industrial, commercial, medical)
• Compatible with microcontrollers like Arduino and ESP32
• Low power consumption
• Compact and easy to integrate into systems

Pinout Description:

• Red: VCC (Power Supply, typically 5V)
• Black: GND (Ground)
• White: Signal (Output signal, typically analog)
• Green: Excitation (Excitation voltage input)

Sample Working Code for Arduino:

// Load Cell Example Code with HX711 Amplifier

#include "HX711.h"

// Define the pins for Load Cell
#define DOUT  3
#define CLK   2

HX711 scale;

void setup() {
  Serial.begin(9600);
  scale.begin(DOUT, CLK);
  scale.set_scale(2280.f);  // Adjust the scale factor for calibration
  scale.tare();             // Reset the scale to 0
}

void loop() {
  long reading = scale.get_units(10);  // Get the average of 10 readings
  Serial.print("Weight: ");
  Serial.println(reading);  // Display weight value
  delay(500);               // Delay between readings
}
