Automate Sprinkler System Using ESP32

User Story

Title: Automate Sprinkler System Using ESP32

As a homeowner, I want to automate my sprinkler system using an ESP32 microcontroller, So that I can efficiently manage my lawn watering schedule remotely and ensure optimal water usage.

Acceptance Criteria

• System Setup
  • The ESP32 microcontroller is integrated with the existing sprinkler system.
  • The ESP32 can control the opening and closing of the sprinkler valves.
• Remote Control
  • I can control the sprinkler system remotely via a mobile app or web interface.
  • The mobile app/web interface displays the current status of the sprinkler system (e.g., on, off, running time).
• Scheduling
  • I can set a watering schedule (e.g., specific days and times) through the mobile app/web interface.
  • The system should allow for multiple schedules to be set for different zones.
• Weather Integration
  • The system integrates with a weather API to adjust watering schedules based on weather conditions (e.g., rain delay).
  • I receive notifications about schedule changes due to weather conditions.
• Manual Override
  • I can manually start and stop the sprinkler system through the mobile app/web interface at any time, overriding the schedule.
  • The manual override option should be easily accessible and user-friendly.
• Water Usage Monitoring
  • The system tracks water usage and provides reports/analytics through the mobile app/web interface.
  • I can view historical water usage data to optimize watering schedules.
• Notifications and Alerts
  • I receive notifications for any system errors or issues (e.g., valve malfunction, low water pressure).
  • I can set up custom alerts for specific conditions (e.g., excessive water usage, missed watering).

Requirements

Hardware Requirements

• ESP32 Microcontroller
  • Must have sufficient GPIO pins to control multiple sprinkler valves.
  • Must support Wi-Fi connectivity for remote access.
