This Instructable describes how to make a small weighing scale using readily available off the shelf parts. Arduino – this design uses a standard. At the Restart Project in London we hold repair events where members of the public are invited to bring in all manner of electrical and electronic items for repair , so as to save them from landfill.
I found a dead scale at work, the electronics were fried. I figured the load cell inside was still goo and would be fun to hack.
DIY scale using HX7and arduino with 0. Weigh objects, and make decisions based on weight. HX7Weight Scale component (Picture 1), and drop it in the design area. Find this and other hardware projects on Hackster.

Compared with the same type of other chip that integrates the peripheral circuits including power supply and on-chip clock oscillator which other similar types . The load cell will be connected with the HX7Module. FREE DELIVERY possible on eligible purchases. The challenge is to build a high-precision scale and to process its data so that it can be consumed in real-time by online apps.
So i decided to try it, I had an arduino UNO, a load cell and an LCD. After a long run, I decided to rely on a DFrobot hx711. After a bit of study on how to connect the converter I . The scale electronics will be left intact. The electronics of the scale that I used has a dual-slope integrating ADC that has been built with some integrated circuits. School of Computer and Information Engineering, Xiamen University of Technology.
The following article will describe how to build up a simple cheap yet very effective 5KG (max) kitchen weight machine for a penny ! Change the strain gauge for a bigger capacity and your bathroom scale is just ready – both are just the same. HX7Load Cell Amplifier, Weighing Scale Design. HX7is a precision 24-bit analogto-digital converter (ADC) designed for weigh scales and industrial . A variable called scale oftype int is declared and initialized with 1. By default it is set to which is Celsius.
Ifyou wish you can change this to – for Fahrenheit. An integer to store the pin being used for the button is . Though the interface to the HX7is quite straightforwar I decided to use a library and after calibrating the scale. As you know from my profile (or not) one of my passion is beekeeping. My apiary is located 50km from my house.
Everyday I study and work casual. By this, I do not have time to inspect the apiary. In the online store I found scales that send data through the GSM network. This weight would be a great idea, .
