WATER LEVEL & TEMPERATURE MONITOR WITH TFT GRAPHICS

Abstract

This project presents the design and implementation of a Water Level and Temperature Monitoring System using ESP32 with a TFT Graphical Display. The main objective of this system is to monitor the water level and water temperature continuously and display the information in a clear and easy-to-understand graphical format. The system helps reduce manual monitoring and improves the efficiency of water management. The system also includes LED indicators and a buzzer to provide instant alerts based on the water level. A green LED indicates a normal water level, a yellow LED indicates a medium level, and a red LED along with a buzzer warns the user when the water level is very low or reaches a critical condition. These visual and audio alerts help users take quick action and prevent water-related problems. An ultrasonic sensor is used to measure the water level in the tank, while a temperature sensor measures the water temperature. The ESP32 microcontroller collects data from these sensors, processes it, and displays the results on a TFT display using graphical indicators such as water level bars, numerical values, and temperature readings. This graphical interface allows users to understand the tank status quickly and accurately. The system provides real-time monitoring, making it easier to detect conditions such as low water level, full tank, water overflow, or abnormal temperature. By providing continuous updates, the system minimizes human effort, reduces water wastage, and improves the overall reliability of water storage management. The proposed system is low-cost, energy-efficient, user-friendly, and easy to install. It can be expanded in the future by adding IoT technology for remote monitoring through a mobile application, cloud data storage, automatic pump control, and alert notifications. A prototype of the system was successfully developed and tested, demonstrating accurate and reliable performance under different water levels and temperature conditions. This project is suitable for residential water tanks, industrial storage tanks, agricultural irrigation systems, laboratories, and other water management applications, where continuous monitoring is essential for efficient operation and resource conservation.
