# Cloud Smart Irrigation

Day 99 of the 100 Days 100 IoT Projects collection. Board: ESP32.

AWS-hosted Node-RED waters plants based on DHT22 and soil data from the ESP32. Irrigation with a cloud brain.

## How it works

Soil and DHT22 data rise from the ESP32 to a Node-RED instance on AWS, where the watering logic decides when the pump runs. The intelligence lives in the cloud; the board just senses and switches. Irrigation with a brain that never sleeps.

## What you'll learn

- Cloud-based control logic
- Remote pump actuation
- AWS-hosted automation
- Sense-decide-actuate split
