Before the load cell is connected to the hx711 weight sensor it should be mounted on the two plates.
Scale mat raspberry pi.
We just need the final code.
Power on your pi i am assuming you have already installed raspbian and it boots up and go to your raspberry pi terminal window.
If you have a raspberry pi 1 or 2 we will have to use one of our usb ports to plug in an adapter.
On the raspberry pi install the following.
As hardly any scales work analogously it is of course also possible to measure weights with a digital raspberry pi scale.
From raspberry pi tutorials.
Things used in this project.
Raspberry pi scale assembling.
Raspberry pi smart scale.

This is a fun easy project that combines a wii balance board a raspberry pi and an online data analytics platform.
That s why we ve made a hackable weight tracking text messaging scale with a sense of humor.
Through this project you will learn how to make a precise raspberry pi kitchen scale.
As the scale will broadcast live data we will use socket io.
First we will discuss the setup for our system.
Raspberry pi kitchen scale as most scales do not work analogously it will also be possible to measure weights with a digital raspberry pi scale similarly to the arduino.
Between the screw and the load cell there should be a.
Power on your pi i am assuming you have already installed raspbian and it boots up and go to your raspberry pi terminal window.
For this i made markings with a ballpoint pen on the wooden boards where the screws come in.
This can be used in various applications as the weight value ranges which can be measured are also almost unlimited.
I hope this example shows that it can be really easy to transfer the weight from a scale to a raspberry pi.
Running on the device is a script.
If you have a raspberry pi 1 or 2 we will have to use one of our usb ports to plug in an adapter.
With a drill i drilled the holes and inserted the screws.
Read from the serial port and transmit the code over.
The edge is a raspberry pi that has been wired to a photocell light sensor.
The raspberry pi 3 comes with bluetooth built in all we need to communicate with the wii balance board.
While this demo is small aka uses a single raspberry pi device you can actually scale this demonstration with thousands of devices using the same setup.
Now your raspberry pi can keep you in check as you pack on the holiday pounds.
