Hello,
Your requirement seems very interesting for us as we are doing multiple project in Weigh scale applications.
We have designed hardware using Nuvoton controller with ESP8266 wifi controller for Strain gauge based load cell sensors. Through the firmware development, we achieved very steady and accurate weight measurement dat with 5 to 10 gm accuracy. We can leverage our past experience and can quickly implement the firmware for mentioned specifications.
Please connect here so we can exchange our past work in Weigh scale applications and also discuss the desired solution for your requirements.
Thanks
Bhavin
