ESP32-Based Intelligent Weight Tracking System

Smart Shelf Weight Monitoring System (ESP32 + HX711 + Web Interface)

Project Description:
I am developing a final-year Electrical & Electronics Engineering project and need assistance building a smart weight monitoring system for a single shelf.

The system will measure and track weight changes in real-time using a load cell sensor and transmit the data to a web-based interface.

Hardware Requirements:

ESP32 microcontroller (Wi-Fi enabled)
HX711 load cell amplifier
Load cell (weight sensor)
Stable and accurate measurement (handle noise and drift)

Software Requirements:

ESP32 firmware (C/C++ / Arduino framework)
Real-time data acquisition from HX711
Wi-Fi communication (HTTP or MQTT)
Data transmission to a web server

Web Interface:

Simple dashboard (web-based)
Display current weight in real-time
Show changes (add/remove items)
Optional: alerts when weight changes beyond threshold

Key Challenges:

Noise filtering and stable readings
Calibration of load cell
Handling drift over time
Reliable wireless communication

Deliverables:

Working ESP32 code
Web interface (basic but functional)
Documentation (setup + explanation)
Optional: suggestions for system improvement

Preferred Skills:

Embedded systems (ESP32)
Sensors & signal processing
Web development (basic dashboard)
IoT systems
