GREATZT Digital Load Cell Weight Sensor 1KG 5KG 10KG 20KG Portable Circuit Diagram In this project, we design a portable, precise, and self-contained weighing system using an HX711 load cell, Arduino Nano, OLED display, DS18B20 temperature sensor, battery voltage amplifier, on/off switch, calibration, and tare buttons. Project Features. Precise Weight Measurement: High accuracy measurement with HX711 ADC module.
A load cell is an application of strain measurements relating to weight measurement. A load is applied to a strain gauge, which causes the gauge to strain a certain amount and output a voltage proportional to the applied load. This relationship between strain and voltage is used in many applications where weight measurement is important.
Arduino Weighing Scale with Load Cell and HX711 Circuit Diagram
In this tutorial, you will learn about the load cell module, its applications and its operation. Also, you'll see how to use the load cell module with Arduino. Then after learning about calibrating the load cell, you will create a digital scale that can measure the weight with an accuracy of 0.0001 grams and also a force gauge. What You Will
This change is proportional to the force exerted, allowing for accurate weight measurement. Proper Installation of Load Cells. Correct installation is vital for obtaining accurate measurements from load cells. Here is a step-by-step guide for you to follow. Mount Securely: Ensure the load cell is firmly mounted to a stable structure. The load cell we're using is usually sold together with an HX711 amplifier. So, that's the amplifier we'll use. HX711 Amplifier. The HX711 amplifier is a breakout board that allows you to easily read load cells to measure weight. You wire the load cell wires on one side, and the microcontroller on the other side. The digital bathroom scale is a strain gage-based load cell device. While classic mechanical scales use a series of levers to distribute the applied weight and drive a spring connected to a mechanical dial, most of today's digital models use multiple strain gauge-based load cells to calculate your weight.

Check the arrow on the load cell. It tells us the direction that we need to apply force. You can assemble the load cell as shown in the figure above using metal strips. Just attach the metal strip on the load cell using bolts. Or you can simply attach bottle caps with bolts by making a hole in the bottle caps as I did in the image below.
