AutoRigation

AutoRigation is an innovative IoT-based irrigation system designed to optimize water usage by automatically adjusting watering schedules based on real-time sensor data. By monitoring soil moisture, temperature, light, humidity, and weather conditions, AutoRigation delivers the right amount of water at the right time—minimizing waste and ensuring optimal plant health.

Project Overview

AutoRigation leverages real-time sensor data collected via an Arduino/ESP32-based prototype and a suite of sensors to drive a smart, automated irrigation system. The system collects data on temperature, humidity, soil moisture, light intensity, and even weather conditions to determine the optimal irrigation schedule. Both the hardware (Arduino code) and the web dashboard (React project) work together to maximize water efficiency and promote sustainable water use.

Hardware Prototype

Our hardware prototype consists of:

• A microcontroller (ESP32 or similar) with WiFi capability.
• Multiple sensors including:
  • DHT22 for temperature and humidity (see DHT22.h).
  • LDR for ambient light measurement (LDR.h).
  • Gravity Soil Moisture Sensor for soil moisture (refer to sms.h).
• A relay controlling a water pump/valve.
• WiFi connectivity for sending sensor data and receiving commands from Firebase.

Key pin configurations and system parameters are defined in pins.h.

Arduino Files

The repository includes all the Arduino source code necessary to run the AutoRigation prototype:

• code_crackers.ino
  The main Arduino sketch that ties together all functionalities.

• DHT22.h
  Handles temperature and humidity readings using the DHT22 sensor.

• LDR.h
  Reads ambient light levels from a photoresistor.

• irrigation.h
  Contains functions for controlling the relay, calculating water usage, and determining when to irrigate.

• firebase.h
  Manages connectivity to Firebase, sending sensor data and receiving configuration updates.

• pins.h
  Defines hardware pin assignments, WiFi credentials, and Firebase configuration parameters.

• sms.h
  Contains functions for interfacing with the soil moisture sensor.

• timenow.h
  Uses NTP to synchronize time.

• weather.h
  Fetches and parses weather data (e.g., rain probability).

Web Dashboard

The web project, built with React, provides a user-friendly dashboard to monitor and configure the AutoRigation system. Key features include:

• Real-Time Monitoring:
  Displays sensor data (temperature, humidity, soil moisture, light) and water usage logs retrieved from Firebase.

• Parameter Configuration:
  Users can adjust irrigation parameters such as flow rate, temperature thresholds, and soil moisture settings through an intuitive UI.

• API Documentation:
  A dedicated page (ApiDocumentation.jsx) details the REST API endpoints for sensor data, water usage, system parameters, and more.

• Connectivity Indicators & Chat Assistant:
  The dashboard displays device connectivity status (based on the browser’s network status) and includes a floating Chat Assistant for additional support.

All source code for the web project is located under the src/ directory. To run the web project, see the Installation & Setup section below.
