[Tutorial] : Automatic Sorting Trash Bin with Favoriot IoT Platform

1. Project Concept

This project develops a smart trash bin that can automatically sort organic and non-organic waste using sensors and is connected to the Favoriot IoT Platform for real-time data monitoring.

Main Components:

• Color Sensor (TCS3200) – Detects waste type based on color.
• Weight Sensor (Load Cell + HX711) – Measures waste weight.
• Servo Motor – Moves the waste sorting mechanism.
• Arduino Uno – Controls the entire system.
• ESP8266 WiFi Module – Sends data to Favoriot IoT Platform.
