About This Architecture

ESP32-based smart irrigation and roof control system integrates soil moisture, temperature-humidity, and rain sensors to automate watering and weather protection. The ESP32 MCU processes sensor data and triggers a relay module to control the water pump and a DC motor for roof actuation, with cloud connectivity via IoT platform for remote monitoring and manual override capability. This architecture demonstrates sensor fusion and dual-actuator control in a single embedded system, solving the challenge of coordinating irrigation with weather conditions while maintaining manual fallback.

How do I build an ESP32 smart irrigation system that automatically controls a water pump and roof based on soil moisture and rain detection?

This diagram shows a complete ESP32 architecture where the MCU reads soil moisture, temperature-humidity, and rain sensors, processes the data, and triggers a relay module to control the water pump and a DC motor for roof actuation. Cloud connectivity enables remote monitoring and control, while manual switches provide override capability for user intervention.
