Snapklikcom 2PCS Digital Load Cell Weight Sensor 1kg 5kg 10kg 20kg Circuit Diagram The load cell has two outputs, a minus and a positive output, the difference of these will be proportional to the weight. The amplifiers requires a +15V and -15V connection. The output of the amplifier is connected to an Arduino which needs a 5V connection, where the analog values will be read in and re scaled to a weight output. 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. 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.
In this post I have explained about strain gauge based load cell. We will be exploring what Strain Gauge is, what Load Cell is, temperature effect on strain gauge, temperature compensation with Wheatstone bridge and Load cell amplifier HX711, and finally I have explained how to build an Arduino based weighing scale machine by implementing load cell as the weight sensor. 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.
How to use a Weight Sensor / Load Cell + HX711 with an Arduino Circuit Diagram
OVERVIEWWe've all used a scale to determine the weight of something at some point in our lives.Using a Load Cell or Weight sensor you can add this capability to your Arduino projects.In this tutorial we will see how to connect, calibrate and display the weight on a small OLED display, and by using a rotary encoder we will be able to change the units from: grams, kg or pounds.We will be using 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. 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.
