An iot-based soil moisture monitoring and automatic irrigation control system

Abstract

The present invention is related to an IoT-based soil moisture monitoring and automatic irrigation control system. The present invention relates to an automated smart irrigation system designed to optimize agricultural water usage through real-time monitoring and intelligent control. The system employs soil moisture sensors, temperature and humidity sensors, and a microcontroller-based processing unit to automatically regulate water supply based on environmental conditions and plant requirements. A motor-pump control unit activates irrigation only when soil moisture falls below a predefined threshold, ensuring efficient water utilization. Additionally, the system integrates wireless communication via Bluetooth or IoT modules, enabling users to monitor and operate the system remotely through a mobile device. This invention reduces manual labor, prevents over-irrigation and under-irrigation, increases crop productivity, and supports sustainable precision agriculture practices. The system is cost-effective, user-friendly, and suitable for farms, gardens, greenhouses, and water-restricted environments.
