We are interfacing 40Kg load cell to the arduino using HX711 Load cell amplifier module. For this purpose, we useHX711 amplifier sensor. using YZC-161B Sensor example code, circuit, pinout library This sensor is called as the load cell, so in this project, we will using this load cell as our Arduino weight sensor. Then connect DAT (data) pin to Arduino Analog pin A3 and connect CLK (clock) pin to Arduino analog pin A2. Thanks Lefty, so I was searching for the wrong thing, that's why I couldn't find anything. I am doing my experiments with a 20 kg load cell, but the same principles apply for other types of four-wire load cells. ... We chose the red and black wire pair to be the power wires of the load cell. Using a Load Cell or Weight sensor you can add this capability to your Arduino projects.

Lift the weights from the module and send the letter t. Then put a specific weight on the sensor and enter its weight. I got this pressure sensor from an old electronic kitchen scale, and I found no info about it on the internet. Arduino Code for Load Cell // Load cells are linear. You most likely apply a regulated DC voltage, positive to red, ground to the black. 3. With the HX711 and load cell together with the Arduino Nano, you can create … Here the need of power supply for load cell and instrumentation amplifier solved by Arduino power pins. If you aren't familiar with the following concepts, we recommend reviewing them … Infrared (IR) Transmitter. Ask Question Asked 5 years, 8 months ago. Focus on one thing and be the best at it. Arduino boards like the UNOh… The portion of code below is copied from the sketch which contains variables you need to know to set up the firmware successfully. The load should show properly. 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 we will learn how to build an Arduino based weighing scale machine by implementing load cell as the weight sensor. Weight sensor / load cell not working. The first thing that about Load Cells that always comes to my mind is the circuit which amplifies the load cell's signal, Usually the load cell signal changes in a low mv range, so you have to put a high gain circuit in the way of the signal, which amplifies signal and NOISE. Then this amplified value is fed to the Arduino where the output of HX711 is converted into the weight values in grams. This circuit is designed for getting reading at serial terminal if you need to add display refer LCD interface with Arduino. 5kg load cell - Load cells are specially shaped metal parts that have strain gauges glue to them. It only takes a minute to sign up. Smart Coffee Table. When force is on the load cell, the spring element is slightly deformed, and unless overloaded, always returns to its original shape. If you are planning on using load sensors 1 you will need to obtain or purchase four units. Scale is designed with -+0.01kg accuracy and switches are used to calibrate digital weight scale.
