Micro-Controller Based Automatic Irrigation System by Sensors

Abstract

Controlling in irrigation is done by microcontroller and sensors. It`s comprised from microcontroller (atmega32), soil moisture sensor, temperature sensor, solenoid valve, sprinklers and rain expectations sensors. And it`s a program of geographical information done by the internet. The soil moisture sensor measures the moisture of soil and it is output is considered as an input to microcontroller which compares it with the less value of soil moisture that preserves plants growing. When it equals the less value or it is less than it, the microcontroller reads the output of rain expectations which is a photo of rainy clouds taken by satellites. If there is no pictures of white clouds that is been captured the valve is opened for irrigation and if it`s captured the valve is closed for the coming rain. The irrigation sprinklers give a high productivity and provide a great deal of water compared by traditional irrigation.
