Smart Weighing Scale for Meat with Integrated Temperature Sensing and Wireless Connectivity
Quispe Jul 07,2025
This project presents the development of a smart electronic scale specifically designed for weighing meat products, including refrigerated or frozen items. The system integrates a high-precision load cell amplifier (HX711) for force measurement and a non-contact infrared temperature sensor (MLX90615) to monitor surface temperature. A dual-microcontroller architecture is used: the STM32 handles sensor acquisition and signal processing, while the ESP32-C3 provides Bluetooth and Wi-Fi communication...
