UNIT Scales is a high precision low-cost I2C port weighing sensor, with a total weighing range of 20kgs. This project is a digital weight scale that utilizes an Arduino Nano microcontroller, an HX711 bridge sensor interface, and a load cell to measure weight. 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, When running the HX711_full_example I get increasing values at each reading: HX711 Demo Initializing the scale Before setting up the scal I'm using the HX710b pressure sensor hooked on Arduino Uno R3. Contribute to Ginger-Stone/The-Scale development by creating an account on GitHub. A Node MCU, HX711, LCD(I2C) and Firebase project. i2c. It should be noted that it is the first time that I try to use this protocol Hi, my problem is that values shown for temperature and humidity are 255 but connections are ok because I tested it with example code from AHTxx library. The built-in calibration algorithm calibrates the weight information with one key and eliminates the need to run a I2C Address: 0 x 64 / 0 x 65 / 0 x 66 / 0 x 67 Af ter the address is modified, it will take effect af ter the sensor is pow ered off and restar ted Description. 3V/5V range. Once the hardware has been modified to set an alternate I2C address, what are the required code changes? To use an alternate, non-default address, it must be explicitly called out in user code. Hello friends, I am in the final stages of building an ESP32 based coffee scale that will measure the output of my grinder. 94 x 1. 60µs Power down: PD_SCK Power down Normal Fig. I have to connect to an Arduino Mega, 9 I2C sensors (in particular humidity and temperature sensors). This library provides the code required to use an Arduino, the HX711 module and a strain gauge load cell to build a scale, force gauge or many other pressure or force sensitive projects.

The Weight I2C Unit is a weight acquisition transducer unit that employs the "STM32+HX711 chip" solution, achieving precision weight measurement with 24-bit accuracy through I2C communication. 75. The built-in calibration algorithm calibrates the weight information with one key and eliminates the need to run a i2c. The load cell has four wires, Description. The device communicates over the i2c bus, my code is compiling and it identifies the scale on the address it is expected to be on. 9V to Barrel Jack Connector. TRANSMITTER for writing mode , i2c. What is the I2C Address? The I2C address is a unique Normally I would be able to use multiple I2C devices connected in row, but the HX711 has no I2C address, because it's no I2C device. DFRobot_HX711_I2C Library for Arduino In this tutorial, it is shown how to utilize an Arduino Uno, a HX711 breakout board, and a load cell in order to measure weight. read()¶ On HX711 board you will find E+/E-, A+/A- and B+/B- connections. . address(id, device_addr, direction) Parameters¶ id bus number; device_addr 7-bit device address.
