MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202541122499 A) filed by Nandha Engineering College, Erode, Tamil Nadu, on Dec. 5, 2025, for 'smart water level and quality monitoring system.'
Inventor(s) include S. Shanmugapriya; R. Mano; S. Praveena; and M. Priyadharshini.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "This invention presents a non-contact, high-resolution Water Level Monitoring System utilizing the Arduino microcontroller platform and an HC-SR04 ultrasonic sensor. The system is designed to provide precise, real-time data on the fluid level within any storage container, overcoming the limitations of traditional fixed-point mechanical sensors (like float switches). The ultrasonic sensor is mounted above the fluid, transmitting a sound pulse and measuring the time-of-flight of the returned echo to calculate the distance to the water surface. The core innovation lies in the software-based calibration and linear mapping. The system is rendered universally adaptable to tanks of varying sizes and irregular geometries by defining two key parameters: the distance to the empty tank bottom (MAX\_DISTANCE\_CM) and the distance to the full waterline (MIN\_DISTANCE\_CM). The Arduino firmware processes the raw distance reading and translates it into a continuous, quantitative percentage of fullness (0- 100%). This continuous reading enables high-resolution monitoring for applications such as industrial fluid inventory management, irrigation scheduling, or smart home cistern management. The output is delivered via serial communication for immediate display and serves as a digital foundation for further integration with alerting systems or data logging mechanisms. The final product is a cost-effective, durable, and easily deployable solution for accurate fluid level assessment."
