Climate-Adaptive IoT Drip Irrigation System

An IoT-based smart irrigation solution designed to optimize water usage in agriculture using soil moisture sensors, weather data, MQTT communication, and cloud-based dashboards. The system adapts irrigation schedules based on real-time soil conditions and climate factors, promoting sustainable farming practices.

This project is currently under development as a major interdisciplinary project (ECE + CE).

Features

• Real-time monitoring of soil moisture levels.
• Automated irrigation control using solenoid valves.
• MQTT communication between sensors, controllers, and cloud.
• Cloud dashboard for live visualization and reports.
• Weather integration for climate-adaptive decision-making.
• Optional solar-powered setup for energy efficiency.
• Simulation tested using Wokwi and integrated into project repo.

Tech Stack

Hardware: Soil Moisture Sensors, Solenoid Valves, Microcontroller(Rasberry pi wifi module)

Backend: Node, Express,Monogo DB

Communication: MQTT

Frontend/Dashboard: React

Simulation: Wokwi

Wokwi Simulation

The Wokwi simulation files are included under the WOKWI folder

• To run:
  • Open the WOKWI folder in Wokwi(site)
  • Upload the JSON files
  • Run the simulation to test soil moisture values and irrigation logic.
