# Blynk Smart Irrigation

Day 47 of the 100 Days 100 IoT Projects collection. Board: XIAO.

A XIAO ESP32-S3 waters plants on schedule through a pump and relay, supervised from Blynk. Automated gardening with phone oversight.

## How it works

On a schedule — or on demand from the Blynk app — the XIAO ESP32-S3 energizes a relay that runs the water pump for a set duration. Soil readings can gate the cycle so dry soil gets water and wet soil does not. Phone-supervised gardening with the board doing the daily work.

## What you'll learn

- Irrigation automation
- Pump relay control
- Scheduled actuation
- Soil-gated watering logic
