Posted about 4 years ago

$10-30 USD

Paid on delivery
The application should measure weights up to 200kg, through 4 load cells of 50kg connected to the HX711 module. The code must run on NodeMCU. Attached photos with mounted scale. The scale should start by informing the current weight on the scale. With known initial weight, the weight of the cylinder informed by the user must be subtracted. The IDE Arduino Console should display: 1. Current weight on the scale 2. Bottle weight (informed by the user) 3. By net mass (informed by the user) 4. Total weight of gas in the cylinder ([login to view URL] weight on the scale - 2. Weight of the cylinder) Sensors: [login to view URL] [login to view URL],searchweb201602_8,searchweb201603_53 [login to view URL],searchweb201602_8,searchweb201603_53

Hello, I am Anthony from Sri lanka. I have 7 years of experience in the field of electronics. Currently I am working as a full time freelancer and I have state of the art electronic lab. Why you should hire me ?? *** I have state of the art electronic workshop. *** I have worked with many micro controllers and modules. I have developed my own libraries to work with most of popular modules. *** My workshop is equipped with, ** PCB printing materiels ** 3D printing (Both DLP & FDM) **Various kinds of breakout boards **Qualified developers *** At some point after creating the prototype, if you are willing to take your idea to commercial level (mass production) I can help you with that since I have many reliable contacts in China. I would like to start working with you in order to bring your idea into reality. Please contact me if you are interested. We can discuss more. Thank you Anthony

Hi, I have done a project like this exactly one year ago. Instead of 1 weight measuring device i did accumulated data from 20 devices each having 4 load cells. I would like to know your requirements and can discuss about the final product. There are no stars in my profile but everybody have to start from somewhere. I will be hoping for your response.
