Hardware Requirements
Arduino Board (e.g., Arduino Uno)
50kg Load Cell with HX711 Weight Sensor
Jumper wires
Software Requirements
Arduino IDE
Code
```cpp
#include <HX711.h>
#define HX711_DOUT_PIN 3
#define HX711_SCK_PIN 2
HX711 scale(HX711_DOUT_PIN, HX711_SCK_PIN);
void setup() {
Serial.begin(9600);
scale.begin();
scale.set_gain(64); // adjust gain to match your load cell
}
void loop() {

Serial.print("Weight: ");
Serial.print(weight, 2);
Serial.println(" kg");
delay(1000);
}
```
Example 2: Weight Measurement with Calibration using Raspberry Pi
This example demonstrates how to use the 50kg Load Cell with HX711 Weight Sensor to measure weight with calibration using a Raspberry Pi board.
Hardware Requirements
Raspberry Pi Board (e.g., Raspberry Pi 4)
50kg Load Cell with HX711 Weight Sensor
Jumper wires
Software Requirements
Python 3.x
RPi.GPIO library
Code
```python
import RPi.GPIO as GPIO
import time
# HX711 pin connections
DOUT_PIN = 17
SCK_PIN = 23
# calibration values
CALIBRATION_FACTOR = 100.0
ZERO_POINT = 0.0
GPIO.setmode(GPIO.BCM)
GPIO.setup(DOUT_PIN, GPIO.IN)
GPIO.setup(SCK_PIN, GPIO.OUT)
def read_weight():
# read 24-bit data from HX711
data = 0
for _ in range(24):
GPIO.output(SCK_PIN, 0)
data <<= 1
data |= GPIO.input(DOUT_PIN)
GPIO.output(SCK_PIN, 1)
# convert data to weight
weight = (data - ZERO_POINT) / CALIBRATION_FACTOR
return weight
while True:
weight = read_weight()
print(f"Weight: {weight:.2f} kg")
time.sleep(1)
```
Note: In this example, you need to adjust the `CALIBRATION_FACTOR` and `ZERO_POINT` values based on your specific load cell and application.
