About This Architecture

Dual-mode precision irrigation system combining autonomous sensor-driven control with remote cloud management for crop protection. The ESP32 microcontroller processes inputs from soil moisture, rain, and temperature-humidity sensors through a decision engine and threshold comparator, triggering relay and motor control for water pump and protective roofing. Sensor data flows to an IoT Cloud Platform via Wi-Fi module, enabling farmers to monitor and override irrigation logic through a mobile application and IoT dashboard. This architecture demonstrates edge intelligence with cloud observability, reducing water waste while protecting crops from adverse weather conditions.

How do I design an IoT irrigation system that combines autonomous sensor control with cloud-based remote monitoring?

This diagram shows a four-tier architecture: sensing (soil moisture, rain, temperature sensors) feeds an ESP32 decision engine that autonomously triggers water pump and protective roofing via threshold comparators and relay modules. Simultaneously, a Wi-Fi module streams sensor data to an IoT Cloud Platform, enabling farmers to monitor and override decisions through a mobile app and dashboard.
