Load cell amplifier i2c

This allows the Arduino to resolve weight mass changes down to the range of the load cell typically g, 1kg, 5kg, or more divided by half the bit depth. Optional 2nd ADC channel, positive input. The brain of the project is as always the arduino, you can use any Arduino board model. Load cell senses the weight and supplies an electrical analog voltage to HX Load Amplifier Module. You should change the OLED address in the following line, if necessary. Load cells are designed to focus stress through beam elements where strain gauges are located.

Esmes' Electronics is a simple introduction to using the micro:bit written by a year 5 student. Learn with Troy by asking for support and, he will post a tutorial here to benefit all of our visitors. Free advice! Add content to this section using the sidebar. Email address Notify me when this product is available:. This can be handy for creating your own industrial scale, process control or simple presence detection.

This version of the SparkFun Load Cell Amplifier features a few changes that you specifically asked for! We have separated the analogue and digital supply, as well as added a 3. Need even more? Check out the SparkFun Qwiic Scale. It has all the features of the HX but with additional library support, a true I2C interface, and no soldering required!

The HX uses a two-wire interface Clock and Data for communication. Check the hookup guide below for more information. Load cells use a four-wire Wheatstone bridge configuration to connect to the HX Each color corresponds to the conventional color coding of load cells:.

The YLW pin acts as an optional input that is not hooked up to the strain gauge but is utilized to ground and shield against outside EMI electromagnetic interference. Please keep in mind that some load cells might have slight variations in colour coding.

HX711 Weighing Sensor Load Cell Amplifier 2 Channel 24bit ADC Module 1pc/5pcs/10pcs

The purpose of this board is to measure the weight of the hive periodically. This allows to detect honey production and swarming. It is an I2C slave that includes a HX for weight measurement. After soldering the device you need to add a bootloader.

Hx vs ina After following this tutorial, all reads from the device returned '', until I swapped the white and black wire pairings - at which point I started to get what looked like real data. If you don't need it or want to use an precision external reference like the REF , you have many more options. I am trying to read in data from a load sensor using a raspberry pi. A simple two-wire digital interface from the HX delivers a signed bit digital value proportional to the beam deflection to the CPU. Other voltage configurations are possible with the INA and you may want to refer to the Data Sheet; link at the end of the The board has terminals that are linked to a INAp, and the pins should give an amplified reading. The masses are read and processed easily. So i started searching the internet and found many tutorials using the load cell and arduino.

SparkFun Qwiic Scale NAU7802 Arduino Library

In this tutorial, it is shown how to utilize an Arduino Uno, a HX breakout board, and a load cell in order to measure weight. The HX is a bit analog-to-digital converter which fits perfectly to weight scale applications. Fortunately, there exist many breakout boards for the HX Therefore, it is very easy to use it in combination with a so-called load cell. As the electrical signal has typically only a few millivolts, it has to be amplified. Preparations for Wiring: In order to easily connect the load cell to the pins of the HX module, you can add DuPont connectors to the wires.

Interface HX711 Load Cell Module w/ Arduino to Build a Digital Weight Scale

An I2C based interface to load cells and other wheatstone based strain gauges. Strain gauges are a lot of fun to play with but they often need complex conditioning and conversion ICs. Qwiic Scale takes care of all the hardware and software concerns and gets you measuring weight! We've written an extensive Arduino library to make reading a load cell over I2C a breeze. Calibrate, get weight, and you're set. This board is one of our many Qwiic compatible boards! Simply plug and go.

This can be handy for creating your own industrial scale, process control or simple presence detection. This version of the Load Cell Amplifier features a few changes that you specifically asked for! We have separated the analog and digital supply, as well as added a 3.

Due to high demand expect some shipping delays at this time, orders may not ship for business days. Please be positive and constructive with your questions and comments. These will be for a project to measure a load and orientation with respect to the horizon. I will either save the serial output via TeraTerm or similar and use JMP for data analysis of said serial data or I will integrate the system with LabVIEW to read the serial output and plot and save the data as needed for later analysis in JMP statistical software. This option would have the simplest wiring and smallest footprint, however I haven't found any success stories with I2C communication with this load cell.
