An IoT based Cost Effective Intelligent Irrigation System for Farmers

This abstract describes the interface between an Arduino microcontroller and various components including a soil moisture sensor, pump, relay, LCD, and GSM module. The Arduino is integrated with a soil moisture sensor to monitor the moisture level in the soil. When the moisture level drops below a certain threshold, the Arduino activates a relay, which in turn powers on a pump to water the plants or soil. Additionally, a GSM module is connected to the Arduino to facilitate communication with a web server and enable SMS alerts. The Arduino uses the GSM module to upload the collected moisture data to a web server, allowing users to remotely monitor the soil moisture levels. This data can be accessed and analysied on the web server, providing valuable insights for efficient irrigation management. LCD will able to give visual feedback.

Furthermore, the GSM module enables the Arduino to send SMS alerts to the user's mobile device. This feature ensures that users are promptly notified whenever the moisture level in the soil falls below the desired range, enabling them to take immediate action and prevent potential damage to the plants.

By integrating the soil moisture sensor, pump, relay, and GSM module with the Arduino, this system provides an automated and efficient solution for monitoring and controlling soil moisture levels. The data upload to a web server and SMS alerts offer convenience and enable timely decision-making for effective irrigation management and plant care.
