AUTOMATIC SMART IRRIGATION SYSTEM

This paper presents an autonomous smart irrigation system driven by a microcontroller unit.By employing sensors to measure soil moisture, temperature, and humidity levels, the system intelligently manages irrigation through control of a water pump and solenoid valves.The setup supports remote access, scheduling, and real-time notifications via integration with communication platforms.Its core objective is water conservation while maintaining ideal soil moisture, ultimately enhancing crop yield, reducing operational costs, and promoting sustainable agricultural practices.Powered by a 9-12V DC supply, the system uses soil probes to assess moisture.When dry soil conditions are detected, the micro controller activates a relay to start irrigation.This smart setup reduces human intervention, increases efficiency in water use, and is economically beneficial for modern farming.
