Precision agriculture · India

Know the soil before you spend a rupee on water or fertilizer.

Dharti-Rakshak is a field probe and cloud agronomist. It reads moisture, temperature, pH, and NPK every few seconds — then tells a farmer what to do next.

Run diagnosis after the probe comes online.

Ask the agronomist

Hindi, Hinglish, or English. Voice or text.

Ask about wheat, rice, irrigation, or fertilizer. I will use the live soil numbers.

Architecture

From probe to prescription.

Judges can follow the chain on the bench: sensor → ESP32 → Firebase → this site → AI.

01

7-in-1 RS485 probe

Modbus holding registers for moisture, temperature, pH, nitrogen, phosphorus, potassium.

02

ESP32 edge node

MAX485 on UART2, sanity checks, 16×2 LCD, 5-second cloud sync.

03

Firebase live node

PUT live_readings, POST historical_logs. Browser listens over WebSockets.

04

Cloud agronomist

Cloudflare Pages functions for diagnosis, chat, leaf vision, and CSV export from D1.

Built for competitions that become products

A soil lab that fits in a field kit.

Designed so a farmer gets an action, a judge sees a working system, and a lab can print a card.
