An activity diagram illustrating the complete cycle of an automated crop irrigation system with time and signal events triggered by soil moisture levels and time of day, including decision nodes for weather forecast analysis before irrigation starts.

Automated Crop Irrigation System - Activity Diagram

This activity diagram illustrates a simplified automated irrigation system that monitors soil moisture levels and makes intelligent watering decisions based on weather conditions, demonstrating the core logic of sensor-driven agricultural automation.

System Overview

Core Functionality:

  • Continuous Monitoring: Real-time soil moisture sensor monitoring
  • Weather Integration: Rain forecast checking to avoid unnecessary watering
  • Automated Decision Making: Smart irrigation control based on environmental conditions
  • Water Conservation: Intelligent scheduling to minimize waste

Key Components

Monitoring Phase:

  • Soil Moisture Sensors: Continuously track moisture levels in crop root zones
  • Weather Service Integration: API connection for real-time rain forecasts
  • System Status: Regular monitoring cycle ensures responsive operation

Decision Logic

Moisture Level Assessment:

  • Low Moisture Trigger: When soil moisture drops below optimal levels
  • Normal Moisture: Continue regular monitoring without irrigation
  • Weather Check: Consult forecast before proceeding with watering

Weather-Aware Irrigation:

  • Rain Expected: Skip irrigation to prevent overwatering and conserve resources
  • No Rain Forecast: Proceed with watering to maintain optimal soil moisture
  • Smart Scheduling: Automatic timing to maximize water efficiency

Irrigation Process

Water Application:

  • Targeted Watering: Apply water to detected dry areas
  • Usage Recording: Track water consumption for optimization
  • Cycle Completion: Return to monitoring mode for continuous operation

System Benefits

Water Conservation:

  • Prevents unnecessary watering when rain is expected
  • Reduces water waste through precise moisture monitoring
  • Optimizes irrigation timing for maximum plant uptake

Automated Operation:

  • Continuous monitoring reduces manual intervention
  • Weather-aware decisions improve irrigation efficiency
  • Simple loop structure ensures reliable operation

This streamlined irrigation system demonstrates how basic sensor technology and weather data can create an effective automated watering solution that conserves water while maintaining optimal growing conditions.
