The HX711 Load Cell Amplifier is a precision 24-bit analog-to-digital converter (ADC) specifically designed for weigh scales and industrial control applications. When combined with an Arduino Mega microcontroller, it becomes a powerful tool for measuring and monitoring weights with high accuracy.
If you’re looking to get started with the HX711 Load Cell Amplifier and Arduino Mega, you’ve come to the right place. In this article, we’ll guide you through the process of setting up and using these components together.
To begin, you will need the following materials:
– Arduino Mega microcontroller
– HX711 Load Cell Amplifier module
– Load cell sensor
– Breadboard
– Jumper wires
Firstly, connect the load cell sensor to the HX711 Load Cell Amplifier module. The load cell sensor should have four wires – red (excitation), black (ground), green (signal +), and white (signal -). Connect the red and black wires to the appropriate terminals on the HX711 module, and the green and white wires to the A+ and A- terminals, respectively.
Next, connect the HX711 module to the Arduino Mega. The HX711 module has four pins – VCC (power), GND (ground), DT (data), and SCK (clock). Connect the VCC and GND pins to the 5V and GND pins on the Arduino Mega, respectively. Connect the DT pin to digital pin 2 on the Arduino Mega, and the SCK pin to digital pin 3.
Now it’s time to write some code. Here’s a simple example to get you started:
#include “HX711.h”
HX711 scale(A2, A3);
void setup() {
Serial.begin(9600);
scale.set_scale();
scale.tare();
}
void loop() {
float weight = scale.get_units(10);
Serial.print(“Weight: “);
Serial.print(weight);
Serial.println(” g”);
delay(1000);
}
Upload this code to your Arduino Mega and open the Serial Monitor. You should see the weight readings from the load cell sensor displayed in grams.
And that’s it! You’ve successfully set up the HX711 Load Cell Amplifier and Arduino Mega. Now you can start experimenting with different load cell sensors and applications, such as building your own digital scale or monitoring weights in industrial processes.
