Schematic Overview: Smart Irrigation System (Standard Europe Version)

1. Power Source (Direct AC/DC):

Uses a standard 220V AC to 12V DC Adapter (Plug-and-play), as electricity is usually available near gardens.

No need for large solar panels or heavy-duty charge controllers.

2. Connectivity (Smart Home Integrated):

MCU: ESP8266 or NodeMCU (Simple WiFi connectivity).

Integration with Google Home or Amazon Alexa using local WiFi.

3. Sensory Input (General Purpose):

Soil Moisture: Standard Resistive Sensors (sufficient for low-salinity, treated water).

Rain Sensor: A simple digital sensor to stop irrigation when it rains (very common in Europe).

4. Plumbing & Actuators:

Valve: Standard Plastic Solenoid Valves for treated water.

Piping: Standard PVC/Vinyl tubing (No UV protection needed).
