Code used: Endail/HX711 run through the python variant HX711-rpi-py; Circuit configuration: Wheatstone bridge connected to HX711; HX711 connected to Raspberry Pi with Data -> GPIO 20, CLK -> I am currently working on a IoT Project in which I am trying to interface my Raspberry Pi 3 to HX711 so that I can read weight readings from my load cell having a range of 200 kg. Then you need to update code. com title: using hx711 with raspberry pi: a python library tutorialintroduction:the hx711 is a precis HX711 Python Library for Raspberry Pi. It can make many interesting applications by acquiring the weight information of objects, such as household electronic scales, daily necessities remaining alarms, and Internet of Things weighing platforms. I have link the 4 differents wires of the sensor (red,black,white,green) to the corresponding one of the HX711. With help of Hi, First post and maybe a noob question. 1. i am wanting to output the values to a separate window once i Raspberry Pi 400 and 500 Raspberry Pi Pico General SDK MicroPython Other RP2040 boards AI Accelerator AI Camera - IMX500 Hailo; Software Raspberry Pi OS Raspberry Pi Connect Raspberry Pi Desktop for PC and Mac Other Android Debian FreeBSD Gentoo Linux Kernel NetBSD openSUSE Plan 9 Puppy Arch A Python library for interfacing with the HX711 load cell amplifier. GitHub. You should verify the read function provides a 16 bit or 24 bit number. GPL-2. For some commands of the installation, root privileges are required. 3V) Pin 15 (VREF) Pin 6 (GND) Pin 14 (AGND) Pin 23 (SCLK) In my script, I use the SpiDev library. can anyone please send correct load cell python code and also I need weight formula with simple and clear explanation. If you have not already installed it, you should do that before testing the joystick. com/ga HX711 weight scale interface with Raspberry PI using SPI - sourcebitt/HX711_SPI Im a python beginner and im doing a project where im trying to connect my HX711 weight sensor and view the data on thingspeak (cloud) . (with Weight Sensor HX711) Using TensorFlow Lite with Google Coral TPU on Raspberry Pi 4. Description. BCM) EMULAT Raspberry Pi Kitchen Scale; An HX711 and Load Cell Arduino Punching Bag; Arduino Scale With 5kg Load Cell and HX711 Amplifier; Basically, the overarching principle is the same in all the projects. I'm looking for information on Chip : HX711 PI : Raspberry pi 3 Load cell to HX711: RED: E+ BLACK:E-WHITE : A+ GREEN: A-HX711 to PI: GND : PIN 25 (GROUND) DT : PIN 21 (BCM GPIO9) SCK : PIN 23 (BCM GPIO11) i am using raspberry pi 3. and hardware schematics 1. #!/usr/bin/env python # HX711. If you look at the hardware, the HX711 is fed with 5V from the PI, then HX711's DT pin connected to Raspberry Pi Pin 29 (GPIO 5) HX711's CK pin to Raspberry Pi Pin 31 (GPIO 6) Is there anything abnormal to you ? Checking with an oscilloscope on GPIO5 and GPIO6 gives me some spike voltage to 4. How to import hx711 library? uPython Hi everyone, I'm trying to connect my hx711 board to my pico and I am having lots of trouble. 10. Place nothing on the scale, run the calibration. The Raspberry Pi is the ideal platform to learn and experiment with new things with Python. To execute a routine demox. Raspberry Pi Pico Simulator. 6 or higher. smart fridge 2. Code Issues Pull requests A scale API for a Raspberry Pi Pico (RP2040) I created a weight scale using a RaspberryPi, Hx711 and 4 load cells. Commented Apr 12, 2019 at 11:10. 3V ! In its current form, it is stripped of a lot of functionality (like tare, unit conversion, etc. 5 watching. We use optional cookies, as detailed in our cookie policy, to remember your settings and understand how you use our website. 2; each HX711 module is connected to separate 3. The clock signal may be generated by any GPIO, there is nothing special about the HX711 clock (apart from a maximum pulse width of 60 µs). Is there a less failure-prone library for handling HX711, can I farm the HX711 reading out to a more efficient, possibly non-interpreted language, or is there HX711 weight scale interface with Raspberry PI using SPI - dudapickler/hx711_SPI Raspberry Pi Pico Weighing Scale with Load Cell & HX711 Module - Full Calibration | HX711 with a Four Wire Load Cell and Arduino | Step by Step Guide | Ardui A place to share your projects, questions, discussion about the raspberry pi pico. I am using the github - Raspberry Pi 3 - SparkFun Load Cell Amplifier - HX711 - Laumas FUN Load cells for wire rope measuring sensor what have you plugged where - I have made below connections: - Load cell plugged to the Sparkfun load cell amplifier HX711 - Load cell amplifier HX711plugged to the Raspberry Pi - HX711 VCC <-> Raspberry Pi pin 2 - HX711 DAT Raspberry Pi HX711 C++ Library, fixed for RPI5. You can use any pin in Arduino. 2. Code: Select all import time from RPi import GPIO from hardware_interface. set_reading_format("MSB", "MSB") #set calibration factor aka reference unit hx. The problem. Python Library for the HX711 load cell amplifier Resources.
