🍎 SMART FRUIT SORTING SYSTEM USING ESP8266

IoT and Smart Agriculture Project

---

---

📖 Project Overview

This project develops an IoT-based Smart Fruit Sorting System using ESP8266 NodeMCU and multiple sensors.

The system automatically detects, measures, classifies, and sorts fruits based on their relative size. Data from the sorting process can be monitored through a web dashboard in real time.

Features

✅ Fruit Detection using IR Sensor

✅ Distance Measurement using SRF05

✅ Automatic Fruit Classification

✅ Servo-based Sorting Mechanism

✅ LCD I2C Monitoring

✅ Real-time Statistics Counter

✅ WiFi Connectivity

✅ Web Dashboard Monitoring

---

🎯 Objectives

• Develop an automatic fruit sorting prototype.
• Apply IoT technology in agriculture.
• Classify fruits according to size.
• Monitor sorting statistics remotely.
• Demonstrate ESP8266 IoT applications.
