Automatic-Smart-Irrigation-System

A system that estimates and measures the moisture of soil in order to operate an irrigation system, restoring water as needed while minimizing excess water use and help the user to monitor the data for further use.

Objective

• To design an automatic irrigation system thereby saving time & power for the farmer.
• To design a proto-type and test it on small scale so that we can create an effective solution for the problems on large scale.
• Eliminating human interaction as much as possible in the process.
• Providing the plants with water only when they require.
• Providing a more modular system for easy upgrades.
• Easy monitoring from anywhere in the world.

Hardware Requirements

• Arduino Uno.
• NodeMCU.
• DS 1307 RTC.
• Soil Moisture Sensor.
• Water Depth Sensor.
• 5v Single channel Relay.
• 16x2 LCD.

Software Requirements

• Arduino IDE.
• Thingspeak READ and WRITE API keys.
