Design of Automatic Plant Irrigation System Using Microcontroller

Abstract

Automatic plant irrigation system rise as a good choice and alternative to the traditional irrigation methods since it is saving time and effort that consumed by the traditional methods where peoples are compelled to stop doing their important activities.

The aim of this thesis is to develop a microcontroller based automatic irrigation system. This system will run automatically by referring to the level of soil moisture. The humidity sensor type connected to the microcontroller is soil moisture sensor YL-69. The level of moisture will be displayed on the LCD screen to inform the user about their plant condition. The system was tested on three soil types (loam, sand and red) .From the results we can observe that the red soil has lower resistance by increasing the water contents.
