🌾 CropTwin Platform

Sensor-less Digital Twin Platform for Smallholder Farmers in India

🚀 Live Demo

📖 Overview

CropTwin is a precision agriculture platform that creates virtual replicas (digital twins) of farms for smallholder farmers. By leveraging free government data sources and scientific crop models, it provides real-time agricultural advisories via SMS without requiring expensive sensors.

The Problem

🌾 Smallholder farmers lack access to real-time crop information
💰 Cannot afford expensive IoT sensors and precision agriculture tools
📱 Limited smartphone access and internet connectivity
🌍 Climate uncertainty leading to crop failures and yield losses

The Solution

✅ Sensor-less: Uses free weather data (IMD) and satellite imagery (ISRO/NASA)
✅ Affordable: <$0.05 per farmer per month
✅ Accessible: SMS-based delivery (no smartphone needed)
✅ Accurate: Scientific crop growth models with 85%+ prediction accuracy
✅ Scalable: Serverless AWS architecture handling 10,000+ farms
