Design and Implementation of an IoT Based Water Level And Soil Moisture Monitoring System

Abstract

The Water Level and Soil Moisture Monitoring System is an IoT-based solution designed to automate the management of water resources, including water tank levels and soil moisture content. This system uses an Ultrasonic Sensor for measuring water levels in tanks, a Soil Moisture Sensor to monitor the moisture content in the soil, and a Node MCU for processing the data and controlling the pumps. The water tank is managed automatically based on the readings from the ultrasonic sensor, while the field irrigation pump is controlled remotely through the Blynk app based on real-time soil moisture data. The system employs a 2-Channel Relay Module to control the activation of two mini water pumps, one for the field and one for the water tank. The water tank pump is automatically activated when the water level falls below a certain threshold, while the irrigation pump is triggered when soil moisture levels drop, ensuring optimal water usage. Additionally, an LCD with I2C provides users with real-time feedback on the system's status, while the Blynk app offers remote monitoring and control from a smartphone. This project aims to optimize water consumption, reduce waste, and enhance the efficiency of irrigation and water tank management in agricultural, residential, and industrial settings. The system is easy to implement, energy-efficient, and scalable, with potential applications in farming, smart homes, parks, and other public spaces. Through this system, water conservation can be significantly improved, contributing to more sustainable resource management.
