E-Scale Solution:

Introduction:

The main controller of this solution is a 32-bit MCU (MG32F02V032) with a 24-bit high precision ADC (MAD2402). The weight of the object is converted into an electrical signal by a pressure sensor, which is processed by the MCU and then the weight data is presented on the display screen. It provides accurate and reliable weight measurement and is suitable for household weighing or commercial /industrial measurement applications.

Features:
