IoT-BASED COMPACT SOIL MOISTURE MONITORING DEVICE

Abstract

The project delineates a sophisticated smart irrigation system leveraging the principles of the Internet of Things (IoT). Central to the system is an Arduino microcontroller, serving as the control hub, orchestrating the operation of a 5V semi-submersible water pump based on real-time soil moisture levels. An integral component of the setup is a Bluetooth module, facilitating seamless connectivity between the user's mobile application and the irrigation system. Through the mobile application, users gain access to sensor data values transmitted via Bluetooth. This bidirectional communication empowers users to monitor soil moisture levels remotely, enabling informed decision-making regarding irrigation needs. The system operates autonomously by activating the water pump when soil moisture levels dip precariously low and deactivating the pump once the moisture level reaches a predefined threshold. This intelligent automation ensures efficient water usage, preventing over-irrigation while fostering optimal soil conditions for plant growth. In essence, this IoT-based smart irrigation system not only introduces automation and precision to the irrigation process but also enhances user interaction through mobile connectivity. The synergy of Arduino control, a submersible water pump, and Bluetooth communication exemplifies a user- friendly and resource-efficient approach to modernizing traditional irrigation practices.
