A Tool to Effectively Water Plants by Measuring the Soil Moisture

CSEF · 2016 Electronics & Electromagnetics

Anay Bhakat · The Quarry Lane School, Dublin, Alameda County

Overview

Objectives/Goals The objective of this project is to create a tool that can water plants with the appropriate amount of water thus reducing water wastage and ensuring proper plant growth. Methods/Materials Arduino Uno,Electronic Soil Hygrometer, Electronic Relay, Solenoid Valve, Bread Board Results The experiments showed that we can effectively water plants by measuring soil moisture. A simulation of watering a 150 sq. ft of vegetable patch using this tool taking into account the daily temperature and precipitation of San Francisco for a year predicted about 6000 gallons of water savings. Conclusions/Discussion This tool is a significant improvement over the current timer based drip irrigation techniques. It saves water and ensures proper plant growth.

Summary statement

I have developed an effective tool to optimize the water given to plants thus reducing water wastage and ensuring proper plant growth.

Help received

I developed the code for the Arduino Micro Controller based on some tutorials that came with the tool. My Father helped review the code for correctness.
