Secure IoT-Based Real-Time Water Level Monitoring System Using ESP32 for Critical Infrastructure

Abstract

Many sectors rely on accurate tank levels, including those dealing with water management, farming, and industry. For effective use, overflow prevention, planning, and resource management, accurate water level measurement is essential. One of the main goals of this research is to find a way to use high-tech sensors to determine how much water is in a tank. In order to gauge how long it takes for sound waves to travel from the water’s surface to return to the sensor, the suggested system makes use of ultrasonic sensors. The technology determines the precise measurement of the water level by analyzing the reflected waves, which in turn determine the distance between the sensor and the water level. We will construct a prototype and test it in a controlled laboratory setting to ensure the system works as intended. An ESP32 microcontroller, an ultrasonic sensor, and a display device showing the water level in real-time will make up the prototype. This study is important because it has the ability to improve water management methods and encourage the efficient use of resources. In order to maximize efficiency, minimize waste, and guarantee sustainable practices, enterprises rely on precise water level assessments. In addition, the system can help find problems with the tank quickly, so maintenance can be done when it’s needed and accidents can be avoided.
