AgroSmart

AgroSmart is a starter web application for the mini project: "AgroSmart - Smart Crop Advisory and Disease Detection System."

This version implements the milestone modules end-to-end:

• User registration, login, and farmer profile
• Crop recommendation with an ML hook (RandomForest) and fallback logic
• Fertilizer recommendation with history and nutrient status chart
• Leaf disease detection with a CNN/Keras hook (when a model exists) and fallback logic
• REST APIs for crop, fertilizer, and disease flows
• SQLite history storage for predictions and recommendations

Tech Stack

• Python 3.13+
• Flask
• SQLite (via SQLAlchemy)

Run Locally

python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
python3 app.py

Then open http://127.0.0.1:5000.

Deploy (Render)

This repo includes a basic render.yaml for a Flask + Gunicorn deploy.

1. Push this repo to GitHub.
2. In Render, create a new Blueprint from the repo (it will read render.yaml).
3. Add environment variables in Render:
   • DATABASE_URL:
     • Recommended: use Render Postgres (managed).
     • If you insist on MySQL: you must run your own MySQL as a private service and set DATABASE_URL to mysql://... (the app auto-normalizes to mysql+pymysql://).
   • SMTP variables: SMTP_HOST, SMTP_PORT, SMTP_USER, SMTP_PASS, SMTP_FROM, SMTP_TLS, SMTP_SSL.

Note: For production, use a persistent disk or external storage for uploads/ (otherwise uploaded images may not persist across deploys).

Recommended persistent paths (if you mount a Render Disk at /var/data):

• UPLOAD_FOLDER=/var/data/uploads
• MODEL_STORE=/var/data/models

Email OTP Verification (Register/Login)

By default, members must verify an OTP sent to their email before logging in.

Set SMTP settings (example):

export REQUIRE_EMAIL_OTP=1
export EMAIL_DELIVERY=smtp
export SMTP_HOST="smtp.yourprovider.com"
export SMTP_PORT="587"
export SMTP_USER="your-agrosmart-email@domain.com"
export SMTP_PASS="your-smtp-password-or-app-password"
export SMTP_FROM="AgroSmart <your-agrosmart-email@domain.com>"
export SMTP_TLS=1
export SMTP_SSL=0

If you want to disable OTP locally:

export REQUIRE_EMAIL_OTP=0

ML Training (Optional)

Crop model (RandomForest):

pip install -r requirements-ml.txt
python3 scripts/train_crop_model.py --data data/sample_crop_data.csv --out models/crop_model.joblib

Disease model (CNN/Keras, requires TensorFlow installed for your machine):

python3 scripts/train_disease_model.py --data_dir /path/to/leaf_dataset --out models/disease_model.keras

Once models exist, the web app auto-uses them; otherwise it falls back to safe placeholder logic.

APIs

• POST /api/crop/predict (JSON)
• POST /api/fertilizer/recommend (JSON)
• POST /api/disease/predict (multipart: leaf_image)

All APIs require login (session cookie).

Admin

Admin dashboard: /admin/ (requires admin login). Admin login page: /admin/login

Promote a user to admin:

python3 scripts/make_admin.py --email you@example.com

Admin login details:

• Use the same email/password as the promoted user.
• After login, admin session is stored separately as admin_user_id.

Weather Auto-fill (OpenWeather)

Set an API key:

export OPENWEATHER_API_KEY="your_key_here"

Then on Crop Recommendation page, click "Auto-fill weather". It uses your Profile location by default.

Languages + Voice Guidance

• Language selector is in the top bar (English/Hindi/Telugu).
• Each module page has Speak/Stop buttons (browser Text-to-Speech via Web Speech API).
