Simple Irrigation System

A week before leaving for 7months in Crete, I realized that my plants would die without me. I quickly designed this simple Irrigation system that could allow my plant to be watered.

The system water the different plants every day at a specific hour. The system also detects when the water tank needs to be refilled and give a LED and sound warning. I used only part that I could find at home, for example, I used the pump motor from a broken hydropulsor, and all the other plastic parts.
