Design and Implementation of Smart Water Level Indicator and Valve Controller

Abstract

Abstract— Accurate and reliable water level monitoring and control are crucial for efficient water management. This research paper presents the design and implementation of a smart water level indicator that utilizes the BC547 transistor-based inductive level measurement technique for discrete level measurement. The system includes an ATmega328p microcontroller that processes the data and controls the different inputs and output lines, such as LEDs and an online interface for remote monitoring and control of water levels. The system uses the inductive properties of water to detect water levels at four different levels. The online interface displays real-time water levels and allows the user to control the solenoid valve to manage water levels. The smart water level indicator provides an efficient and user-friendly solution to water level management, helping to minimize water wastage and promote sustainable water usage. The results of testing demonstrate the accuracy and reliability of the system in monitoring and controlling water levels.
